A 1500 kg sedan goes through a wide intersection traveling from north to south when it is hit by a 2200 kg SUV traveling from east to west. The two cars become enmeshed due to the impact and slide as one thereafter. On-the-scene measurements show that the coefficient of kinetic friction between the tires of these cars and the pavement is 0.75, and the cars slide to a halt at a point 5.39 m west and 6.43 m south of the impact point. How fast was each car traveling just before the collision?

A 1360 - kg car moving at 6.40 m/s is initially traveling north along the positive direction of a y axis. After completing a 90° right-hand turn to the positive x direction in 4.00 s, the inattentive operator drives into a tree, which stops the car in 490 ms. (picture has the question)
A 54.9-kg skater is standing at rest in front of a wall. By pushing against the wall she propels herself backward with a velocity of -1.93 m/s. Her hands are in contact with the wall for 1.09 s. Ignore friction and wind resistance. Find the average force she exerts on the wall (which has the same magnitude, but opposite direction, as the force that the wall applies to her). Note that this force has direction, which you should indicate with the sign of your answer. Number -9.72 Units

A box of unknown mass is sliding with an initial speed vi = 4.90 m/s across a horizontal frictionless warehouse floor when it encounters a rough section of flooring. The coefficient of kinetic friction between the floor and the box is 0.625. How far does the box slide before stopping?
Which answer below is closest to the magnitude of the normal force that the idealized in-run exerts on the 60-kg skier? The 2010 Olympic ski jumping competition was held at Whistler Mountain near Vancouver. During a jump, a skier starts near the top of the in-run, the part down which the skier glides at increasing speed before the jump. The Whistler in-run is 116 m long and for the first part is tilted down at about 35° below the horizontal. There is then a curve that transitions into a takeoff ramp, which is tilted 11° below the horizontal. The skier flies off this ramp at high speed, body tilted forward and skis separated (Figure 4.15). This position exposes a large surface area to the air, which creates lift, extends the time of the jump, and allows the jumper to travel farther. In addition, the skier pushes off the exit ramp of the in-run to get a vertical component of velocity when leaving the ramp. The skier lands 125 m or more from the end of the in-run. The landing surface has…
Daredevil Darla has heard that to avoid injury when jumping out of her rocket she should bend her knees upon landing. Darla has a mass of 74 kg. If just before contact with the ground, she has a downward speed of 7.3 m/s, then. . . (a) In a stiff -legged landing she comes to a halt in 2.0 ms. Find the average net force that acts on her during this time. ( b) When she bends her knees, Darla comes to a halt in 0.10 s. Find the average net force now. (c) During the landing, there are two forces acting on Darla: the normal force from the ground points upward, while her weight force points downward. The average net force acting on Darla includes both of these forces. Taking into account the directions of the forces, find the force of the ground on Darla in parts (a) and (b).
Your friend is catching a falling basketball after it has passed through the basket. Her hands move straight down while catching the ball. It takes about 0.10 s for the player to lower her hands to stop the ball. Assume the mass of the ball is 0.60 kg, and that the ball has fallen a vertical distance of 1.2 m before reaching the player's hand. Determine the average force that her hands exert on the ball while catching it.
Hi please help with the following: After hitting a long fly ball that goes over the right fielder's head and lands in the outfield, the batter decides to keep going past second base and try for third base. The 59 kg player begins sliding 3.40 m from the base with a speed of 4.35 m/s. If the player comes to rest at third base, what was the coefficient of kinetic friction between the player and the ground?
A 49.2-kg skater is standing at rest in front of a wall. By pushing against the wall she propels herself backward with a velocity of -2.08 m/s. Her hands are in contact with the wall for 0.756 s.
