In 2007, Michael Carter (U.S.) set a world record in the shot put with a throw of 24.77 m. What was the initial speed, in m/s, of the shot if he released it at a height of 2.10 m and threw it at an angle of 38.0° above the horizontal? (Although the maximum distance for a projectile on level ground is achieved at 45° when air resistance is neglected, the actual angle to achieve maximum range is smaller; thus 38° will give a longer range than 45° in the shot put.) v0 =

A projectile is fired with an initial velocity of 1000 m/s at an angle of 370 above the horizontal. If air is neglected, the horizontal component of the projectile's velocity after 20 s is: O 16 m/s O 640 m/s O 800 m/s O 600 m/s
The archerfish uses a remarkable method for catching insects sitting on branches or leaves above the waterline. The fish rises to the surface and then shoots out a stream of water precisely aimed to knock the insect off its perch into the water, where the archerfish gobbles it up. Scientists have measured the speed of the water stream exiting the fish’s mouth to be 3.7 m/s. An archerfish spots an insect sitting 19 cm above the waterline and a horizontal distance of 30 cm away. The fish aims its stream at an angle of 39° from the waterline. Does the stream hit its mark?
A firework shell is shot into the air with an initial speed of 60.0 m/s at an angle of 80.0° above the horizontal. The fuse will ignite the shell just as it reaches its highest point above the ground. (a) How much time passes between the launch of the shell and the explosion? (b) Calculate the height at which the shell explodes. (c) What is the horizontal displacement of the shell when it explodes? (d) What is the total displacement from the point of launch to the highest point?
A person on the top of a roof of a building (100 m) drops a ball. After 2s passed, a person who stands at the base of the same building throws a separate ball in the upward direction with a speed of 20 m/s. Assumes the two balls are traveling on the same vertical path. Will the two balls collide with each other? If so, what are their velocities as they collide with each other?
In the homecoming game, the field goal kicker attempts to make a 47 yard (43 m) field goal. He kicks with an initial velocity of 20 m/s at an angle of 60° The field goal posts are 3 m high. Does he make the field goal?
Sofia is playing a game with her friend, Kara, where she throwsM&M candies at Kara and Kara catches the M&M’s in hermouth. They begin standing 1.75 meters apart from eachother. Sofia throws the M&M at an angle of 60 degrees abovethe horizontal with a speed of 4.13 m/s. Kara’s mouth is145 cm above the ground when she catches the M&M. Whatheight above the ground did the M&M leave Sofia’s hand?Hint: Remember, even though the motion in the horizontaldirection is independent of the motion in the vertical direc-tion, they share the same time.
A horizontal projectile is shot with an initial velocity of 29.9 m/s from a height of 6.99 m above the ground. Neglecting air-resistance, what is the direction of the final velocity (in degrees)? Hint: angle measured from the horizontal (+x-axis), positive angles for counterclockwise & negative angles for clockwise.
A father demonstrates projectile motion to his children by placing a pea on his fork's handle and rapidly depressing the curved tines, launching the pea to heights above the dining room table. Suppose the pea is launched at 7.51 m/s at an angle of 81.0° above the table. With what speed (in m/s) does the pea strike the ceiling 1.90 m above the table? m/s
An Olympic diver is on a diving platform 5.20 m above the water. To start her dive, she runs off of the platform with a speed of 1.3 m/s in the horizontal direction. What is the diver's speed, in m/s, just before she enters the water? m/s
The record distance in the sport of throwing cowpats is81.1 m. This record toss was set by Steve Urner of the UnitedStates in 1981. Assuming the initial launch angle was 45°and neglecting air resistance, determine (a) the initial speedof the projectile and (b) the total time the projectile was inflight. (c) Qualitatively, how would the answers change if thelaunch angle were greater than 45°? Explain.
