OK, now you're all mixed up and you slam into the wall with your car (total mass 67 kg) moving at 3.6 m/s. You bounce straight back at 2.6 m/s and somehow determine that the time of contact with the wall was 37.2 ms. What is the magnitude of the force that was exerted on your car?

You throw a 0.350 kg tennis ball horizontally toward a wall. The speed of the ball is 12 m/s before it hits the wall, and it bounces back with the same speed of 12 m/s. If the ball remains in contact with the wall during this collision for 0.025 s, what is the magnitude of the average force exerted on the ball?

For this problem, use the system of the spring-Earth-block system, but do not include the wall or track in your system A spring (spring constant k) is near the bottom of a frictionless loop-the-loop (radius R). The left end of the spring is secured to an immovable wall. The right end ofthe spring is used to launch a block (mass m) around the loop-the-loop 1. Explain why the track does no work on the block, even though it exerts a...

You and your family take a road trip on a long holiday weekend. in a certain section of the trip where the road is particularly uneven, the car goes over a bump that is curved downward with a radius of 23.0 m. See diagram below. the mass of the car and its passengers is 1600 kg. When the car is at the highest point of the bump, its speed is 8.40 m/s. Determine the magnitude and direction of the force...

A baseball with a mass of 141 g is thrown horizontally with a speed of 40.1 m/s (90 mi/h) at a bat. The ball is in contact with the bat for 1.05 ms and then travels straight back at a speed of 45.2 m/s (101 mi/h). Determine the average force exerted on the ball by the bat. Neglect the weight of the ball (it is much smaller than the force of the bat) and choose the direction of the incoming...

When jumping straight down, you can be seriously injured if you land stiff-legged. One way to avoid injury is to bend your knees upon landing to reduce the force of the impact. A 89.8-kg man just before contact with the ground has a speed of 8.70 m/s. (a) In a stiff-legged landing he comes to a halt in 3.21 ms. Find the magnitude of the average net force that acts on him during this time. (b) When he bends his...
