A 20 g ball of clay traveling east at 8.0m/s collides with a 80 g ball of clay traveling north at 2.0 m/s.     Part A What is the speed of the resulting 100 gg ball of clay?   Part B What is the direction of the resulting ball of clay? (in degrees)

Problem 5: A 1.8 kg falcon catches a 0.65 kg dove from behind in midair. What is the speed of the pair of birds right after the catch if the falcon's initial speed was 28 m/s, the dove's initial speed was 7 m/s, and they were moving in the same direction?

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

At a carnival game, two balls are Identical in mass and radius, but one is made of steel and one is made of rubber. The game is to throw them at a bowling pin and try to knock it over. If the balls are thrown with the same speed and hit the same spot on the bowling pin, which Is more likely to knock it over? A. The steel ball B. Without knowing more information, this cannot be answered. C. Both are equally likely since they have the same momentum D. The rubber ball

An archer shoots an arrow toward a 300-g target that is sliding in her direction at a speed of 2.35 m/s on a smooth, slippery surface. The 22.5-g arrow is shot with a speed of 42.0 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 20 g glob of clay traveling east at 3.0 m/s collides with 30 g glob of clay traveling north at 2.0 m/s.  Determine the speed of travel of the resulting 50 g glob of clay.

A 330.0 g bird flying along at 8.10 m/s sees a 17.0 g insect heading straight toward it with a speed of 26.0 m/s. The bird opens its mouth wide and enjoys a nice lunch. What is the bird's speed (in m/s) immediately after swallowing?

A 50-g ball is shot into a chamber attached to a 500-g cart.  After the collision the ball/cart combination moves away with a speed of 3.0 m/s.  Assuming that friction and air resistance are negligible, determine the amount of energy lost in the collision.

An archer shoots an arrow toward a 300-g target that is sliding in her direction at a speed of 2.15 m/s on a smooth, slippery surface. The 22.5-g arrow is shot with a speed of 35.5 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?

1.A charging bull elephant with a mass of 5240 kg comes directly toward you with a speed of 4.55 m/s. You toss a 0.150-kg rubber ball at the elephant with a speed of 7.81 m/s. (a)When the ball bounces back toward you, what is its speed? (b) How do you account for the fact that the ball’s kinetic energy has increased? Explain and draws.
