A springbok is an antelope found in southern Africa that gets its name from its remarkable jumping ability. When a springbok is startled, it will leap straight up into the air—a maneuver called a "pronk." A particular springbok goes into a crouch to perform a pronk. It then extends its legs forcefully, accelerating at 35 m/s for 0.70 m as its legs straighten. Legs fully extended, it leaves the ground and rises into the air. 2 a. At what speed does the springbok leave the ground? b. How high does it go?

A small child is learning to ride a bike for the first time. Her dad decides it would be a good idea to start her on a small hill. The hill is inclined at 3.40° to the horizontal. The child starts partway down the hill, 4.00 m away from her dad, who stays at the top. She starts to wobble, so her dad sprints toward her from rest with an acceleration of 3.80 m/s2. How far has the child gone before her parent catches her?
Alice and Tom dive from an overhang into the lake below. Tom simply drops straight down from the edge, but Alice takes a running start and jumps with an initial horizontal velocity of 25 m/s. Neither person experiences any significant air resistance. Just as they reach the lake below (select all answers that are true) Group of answer choices: None of the above choices are correct. they will both have the same speed. the speed of Alice is larger than that of Tom. Alice reaches the surface of the lake first. They reach the surface of the lake at the same time. Tom reaches the surface of the lake first. the speed of Tom is larger than that of Alice.
Falcons are excellent fliers that can reach very high speeds by diving nearly straight down. To pull out of such a dive, a falcon extends its wings and flies through a circular arc that redirects its motion. The forces on the falcon that control its motion are its weight and an upward lift force—like an airplane—due to the air flowing over its wings. At the bottom of the arc, as shown, a falcon can easily achieve an acceleration of 15 m/s2. Suppose the falcon weighs 8.0 N and is turning with an acceleration of 15 m/s2 at the lowest point of the arc. What is the magnitude of the upward lift force at this instant?A. 8.0 N B. 12 NC. 16 N D. 20 N
While watching the Minty Mania Grand Prix (the first race of the Marbula One 2020 season), you're curious about a few things. You notice that the marbles move downhill during the entire race (the slope of the track changes at different points), and then are lifted back to the starting line by a conveyor belt at the end of each lap. The announcer mentions that the conveyor belt lifts the marbles a height of 40.0 cm, at a constant speed of 0.095m/s, and that the length of the conveyor belt is 52 cm. He also mentions that the length of the track (from start line to finish line) is 10.26 m. You can assume that the marble is already moving at this speed when it starts moving up the conveyor belt. You also know that the mass of each racer (marble) is 6.6 g. To simplify the analysis, you decide to model the force of friction acting on the marble (due to interactions with the track, walls, and other marbles) as a constant 0.002 N force. To satisfy your curiosity, determine the power of the…
A small child is learning to ride a bike for the first time. Her dad decides it would be a good idea to start her on a small hill. The hill is inclined at 3.00° to the horizontal. The child starts partway down the hill, 9.00 m away from her dad, who stays at the top. She starts to wobble, so her dad sprints toward her from rest with an acceleration of 1.40 m/s2. How far has the child gone before her parent catches her?
A toad with mass of 280 g leaps into the air to catch a fly. If the toad's jump was at an angle of 35 degrees with respect to the horizontal, and with an initial velocity of 5.1 m/s, what is its speed (in m/s) when it reaches its maximum vertical displacement?
Chris and Steve push a huge boulder (m = 65 kg) to the top of an 18 m cliff. The boulder is moving with a speed of 6.0 m/s when it tumbles over the edge of the cliff. How fast will it be going when it hits the ground? (no air resistance)
An action figure is placed on a toy car, which is initially at rest. Then the action figure moves through 4 time intervals: The car is pushed until it hits a wall. Then, the action figure slides down a ramp. The action figure flies off of the ramp and hits a wall at the peak of its trajectory, momentarily coming to a complete stop. Finally, the action figure falls into the toybox and comes to rest. Assume that all surfaces, except the final wall, have nonzero coefficients of static and kinetic friction. For each time interval, including the endpoints, determine whether the total work done on the action figure by gravity (?g), normal forces (?N), and friction (?f) is positive, negative, or zero. Neglect drag. The motion of a toy army guy action figure is shown in four different time intervals. The toy is stiff and has a base for standing upright. During interval 1, shown in the upper left, the army guy stands upright upon a car initially at rest. The car is pushed to the right,…
A small block has a horizontal velocity of 4.00 m/s as it slides off the edge of a table. The table is a vertical distance of 0.85 m above the floor. If g = 9.80 m/s2, how far does the block travel horizontally while it is in the air?
A skier is at the top of a hill with height h. Starting from rest, the skier goes down to a flat area. On this flat area, there is a section of the slope with length D where the snow has melted (there is friction here). After passing the melted section, the skier goes up a smaller hill of height h2. At the top of this hill there is a drop off and the skier launches off of it with a horizontal speed. At what horizontal distance from the base of the jump does the skier land?
n a carbon monoxide (CO) molecule, the distance between the oxygen atom and the carbon atom is 1.13 × 10-10 meters. The mass of an oxygen atom is 16 atomic mass units (amu) and the mass of a carbon atom is 12 amu. How far from the oxygen (O) atom is the center of mass of the molecule, in meters? Justify your answer using your equations and rationale used.
Dr. Liu is learning how to juggle. He tosses a tennis ball (probably bad choice since it is so bouncy) up at 2.0 m/s at a height 1.6 m above the floor and attempts to use the other hand to catch the falling ball. The ball hit the floor at his feet. How long was Dr. Liu's tennis ball in the air (between tossing and landing)? Ignore air drag. He should probably practice tossing his juggling ball at the same height and same speed before attempting to juggle. Hint: You can set the final position to be zero.
