- A block of ice with a mass of 2.50 kg is moving on a frictionless, horizontal surface. At t=0, the block is moving to the right with a velocity of magnitude 6.00 m/s. Calculate the magnitude of the velocity of the block after the following force has been applied for 6.0s: a force of 5.00N directed to the right. Calculate the magnitude of the velocity of the block after the following force has been applied for 6.00s: a force of 7.00 N directed to the left.I am driving down the street at 23.4 mi/h and suddenly I see a squirrel. I slam on the brakes in 0.89 seconds to avoid hitting the squirrel. Luckily, he got away. With what force in kiloNewtons did the 455 kg car come to a stop?

- A 5 kg box is sliding on a frictionless surface with a velocity of 6 m/s. It collides with a wall and comes to rest in 0.1 seconds. What is the magnitude of the average force exerted on the box by the wall?During a squash game, a player hits the ball, of 24 g, which is moving toward him horizontally at 150 km/h. The impact between the racket and the ball lasts 1.2 ms and the ball leaves with an identical speed but in the opposite direction as the initial velocity. The ball then hits the wall in front, 8 m away and 18 cm below the height of the hit. What is the average force acting on the ball during the impact?A 850 g cart is released from rest on a frictionless, 45 ∘ ramp, 120 cm from the bottom of the ramp. It rolls down, bounces off a rubber block at the bottom, and then rolls 80 cm back up the ramp. A high-speed video shows that the cart was in contact with the rubber block for 15 ms. What was the magnitude of the average force exerted on the cart by the block measured in newtons?

- 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 69.5-kg man just before contact with the ground has a speed of 8.82 m/s. (a) In a stiff-legged landing he comes to a halt in 4.17 ms. Find the magnitude of the average net force that acts on him during this time. (b) When he bends his knees, he comes to a halt in 0.267 s. Find the magnitude of the average net force now. (c) During the landing, the force of the ground on the man points upward, while the force due to gravity points downward. The average net force acting on the man includes both of these forces. Taking into account the directions of the forces, find the magnitude of the force applied by the ground on the man in part (b).A rifle bullet with a mass of 5 g traveling toward the right at 206 m/s strikes a large bag of sand and penetrates it to a depth of 0.3 m.
