A 160 g baseball is thrown with a speed of 20 m/s. It is hit straight back toward the pitcher at a speed of 40 m/s. The impulsive force of the ball registers at 0.60 milli seconds. What is the average force that the bat exerts on the ball

The lead female character in the movie Diamonds Are Forever is standing at the edge of an offshore oil rig. As she fires a gun, she is driven back over the edge and into the sea. Suppose the mass of a bullet is 0.0142 kg and its velocity is +729 m/s. Her mass (including the gun) is 51.5 kg. What recoil velocity does she acquire in response to a single shot from a stationary position, assuming that no external force keeps her in place?

Alyssa works at the Naval Civil War Museum in downtown Columbus, helping to perform historical re-enactments on the Chattahoochee River. In one re-enactment, a 100.0 kg cannonball is fired from a 1200 kg cannon, with a muzzle velocity of 52 m/s. What is the recoil velocity of the cannon? Assume that frictional forces are negligible, and the cannon is fired horizontally.

A hockey puck (mass 6.00 kg), initially moving in a straight line with a speed of 1.8 m/s is hit with a hockey stick toward the goal. After it is struck, it moves with a speed of 4.4 m/s at an angle of 77 degrees with respect to its initial direction. What is the magnitude of the impulse (in Newton- seconds) that the hockey stick exerted on the puck?

A 72.5 kg projectile is used to deflect a 200 kg boulder heading towards a small town. The projectile is travelling 13.4 m/s in a southwest direction (an angle of 280 north of west). While the boulder is travelling at 8.18 m/s due north. After the impact the projectile comes to a complete rest. What is the velocity of the of the boulder?

As shown in the figure, a metal ball with mass m2 is initially at rest on a horizontal, frictionless table. A second metal ball with mass m1 moving with a speed 3.00 m/s, collides with m2. Assume m1 moves initially along the +x-axis. After the collision, m1 moves with speed 2.00 m/s at an angle of ? = 45.0° to the positive x-axis. (Assume m1 = 0.100 kg and m2 = 0.400 kg.)   (a)  Determine the speed (in m/s) of the 0.400 kg ball after the collision.   (b) Find the fraction of kinetic energy transferred away or transformed to other forms of energy in the collision. |ΔK| / Ki

A 0.2 kg baseball with a speed of 48 m/s is struck by a bat. The ball rebounds and travels in the opposite direction at 52 m/s. The ball was in contact with the bat for only 2 ms. Find the magnitude of the force of the bat on the ball.

Consider the problem of returning a serve in tennis. A serve is hit at a speed of 73.3 m/s, and is hit back to the server with a speed of 51.1 m/s. The ball of mas m = 57 g   is in contact with the racket for 0.01s. (a) What is the magnitude of the impulse imparted to the ball as it is returned to the server? Estimate the magnitude of the average force on the ball.

An amateur golfer swings a golf club, striking a golf ball that has a mass of 55.0 g. The club is in contact with the ball for only 0.00430 s. After the collision, the ball leaves the club at a speed of 35.0 m/s. What is the magnitude of the average force (in N) exerted on the ball by the club?

An incoming tennis ball (mass 0.060 kg) has a speed of 14 m/s. The player hits the ball with a racquet, giving the ball a speed of 30 m/s in the opposite direction. If the contact time is 0.005 s, what is the average force of the racquet on the ball?
