You drop a 15-g ball from a height of 1.5 m and it only bounces back to a height of 0.85 m. What was the total impulse on the ball when it hit the floor? (Ignore air resistance.) Express your answer to two significant figures and include the appropriate units. Enter positive value if the impulse is upward and negative value if the impulse is downward. F-Δt=__________
A 40.0-g bullet moving at a 250.0 m/s passes through a 2.40 cm thick sheet of foam plastic and emerges with a speed of 90.0 m/s. Assuming that the speed change takes place uniformly, calculate the average force that impeded the bullet's motion through the plastic. (Hint: You can apply the impulse-momentum theorem to solve the problem.)
Part A. What is the magnitude of the impulse delivered by the bat to the ball? Part B. If the bat is in contact with the ball for 1.5 ms, what is the magnitude of the average force exerted by the bat on the ball?
An archer shoots an arrow toward a 300-g target that is sliding in her direction at a speed of 2.00 m/s on a smooth, slippery surface. The 22.5-g arrow is shot with a speed of 36.5 m/s and passes through the target, which is stopped by the impact. What is the speed of the arrow after passing through the target? m/s

A baseball of mass m = 0.34 kg is dropped from a height h1 = 2.4 m. It bounces from the concrete below and returns to a final height of h2 = 1.85 m. Neglect air resistance. Select an expression for the impulse I that the baseball experiences when it bounces off the concrete. What is this impulse, in kilogram meters per second? If the baseball was in contact with the concrete for t = 0.01 s, what average force Fave did the concrete exert on the baseball, in newtons?
