When a loaded cannon is fired, which physical variables are affected? Check all that apply. ► View Available Hint(s) the momentum of the cannon the momentum of the system the energy of the system the velocity of the cannon the momentum of the ball the velocity of the ball the temperature of the cannon the temperature of the ball the inertia of the ball the chemical energy the inertia of the cannon P Pearson

A 190-g projectile is fired with a velocity of +730 m/s at a 2.3-kg wooden block that rests on a frictionless table. The velocity of the block, immediately after the projectile passes through it, is +20 m/s. Find the velocity with which the projectile exits from the block. m/s What percentage of the original kinetic energy of the projectile is lost in the collision? %

Lark Brandt won a "Worlds Fastest Smash" competition in the early 2000s. His ping pong ball achieved a speed of 112.5 km/hr. If his ping pong ball had a mass of 2.7 g and hit a wooden block with a mass of 125 g and bounced back with a speed of 45.0 km/hr, what speed (in km/hr) would the wooden block have?

An archer shoots an arrow toward a 300-g target that is sliding in her direction at a speed of 2.45 m/s on a smooth, slippery surface. The 22.5-g arrow is shot with a speed of 37.5 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
