A 47.7-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 0.755 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

A tennis ball is flying east towards the wall with a speed of 41.3 m/s. After bounced against the wall, it's flying west with a speed of 26.3 m/s. If the mass of the ball is 0.1 kg, and the time of collision with the wall is 0.099 seconds, what is the magnitude of the force on the wall during this process in unit of Newton?
A 0.576-kg ball, initially moving with a speed of 2.93 m/s, bounces off a wall and then moves with a speed magnitude half of its original directed in the opposite direction. If the ball is in contact with the wall for 5.2 ms, what is the magnitude of the average force that the wall exerts on the ball? Express your answer in two decimal places, in Newtons.
A 0.065-kg tennis ball moving to the right with a speed of 15 m/s is struck by a tennis racket, causing it to move to the left with a speed of 15 m/s. If the ball remains in contact with the racquet for 0.020 s, what is the magnitude of the average force experienced by the ball?

A car with mass mc=1270kg is traveling west through an intersection with a speed of vc=14.41m/s when a truck of mass mt=1740kg traveling south at vt=6.63m/s fails to yield. The vehicles collide, they stick together, and they slide on the asphalt which has a coefficient of kinetic friction of μk=0.500. Associate the positive x direction with east and the positive y direction with north. a. Using the symbols provided in the palette below as opposed to their numeric equivalents, enter an expression, in Cartesian unit-vector notation, for the velocity of the vehicles immediately after the collision, as they begin to slide as a composite object. b. How far, in meters, will the vehicles slide after the collision?
A tall man walking at 1.10 m/s accidentally bumps his head of mass 3.07 kg on a steel doorjamb. His head stops in 0.019 s. What is the magnitude of the average force exerted by the doorjamb on the man's head?
As part of a safety investigation, two 1400 kg cars traveling at 20 m/s are crashed into different barriers. Find the average forces exerted on (a) the car that hits a line of water barrels and takes 1.5 s to stop, and (b) the car that hits a concrete barrier and takes 0.10 s to stop.
A 50 g ball hits the ground at 19 m/s and rebounds at {v 11b} m/s. If the ball remains in contact with the ground for 200 milliseconds, What is the average force in Newtons applied by the ground on the ball during the bounce?
A 1.2 kg ball is falling in the -y direction at a speed of 25 m/s. The ball strikes the floor and then rebounds with a speed of 10 m/s.

A block of mass m1 = 11.5 kg slides along a horizontal surface (with friction, μk = 0.21) a distance d = 2.15 m before striking a second block of mass m2 = 8.25 kg. The first block has an initial velocity of v = 8.25 m/s. 1. Assuming that block one stops after it collides with block two, what is block two's velocity after impact in m/s? ** answer is NOT 12.3 m/s.
A baseball of mass m1 = 0.46 kg is thrown at another ball hanging from the ceiling by a length of string L = 1.75 m. The second ball m2 = 0.76 kg is initially at rest while the baseball has an initial horizontal velocity of V1 = 3.5 m/s. After the collision the first baseball falls straight down (no horizontal velocity).What is the angle that the string makes with the vertical at the highest point of travel in degrees?
A block of mass m1 = 15.5 kg slides along a horizontal surface (with friction, μk = 0.29) a distance d = 2.65 m before striking a second block of mass m2 = 5.25 kg. The first block has an initial velocity of v = 9.25 m/s. What is the speed of m1, in m/s, right before it collides with m2? Assuming that block one stops after it collides with block two, what is block two's velocity after impact in m/s?
