What would the speed of the puck (in m/s) after being reflected back?

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

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 non-BYU Idaho student is having a snow ball fight. 'Accidentally' a snowball travelling north at 10.0 m/s hits a bicyclist traveling west at 5.00 m/s. The mass of the snowball is 0.750 kg, and the bicyclist is 55.0 kg. What is her final velocity, a. If the snow ball sticks to the bicyclist? b. If the snow ball bounces off with a speed of 2.0 m/s at an angle 20.0° West of South?

A 10 gram bullet is fired from a gun and embeds itself into a 1.0 kg block of wood. After the collision the block of wood skids away at 4.0 m/s. What was the initial speed of the bullet?

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?

Two carts on a track are headed toward each other, and have a head-on collision.Cart 1 has a mass of 2 kg and is traveling at 3 m/s, and Cart 2 has a mass of 3 kgand is traveling at 1.5 m/s. After the collision, Cart 2 has a speed of 0.75 m/s inthe opposite direction it was originally traveling.a. What is the speed and direction of cart 1 after the collision?b. What is the change in energy during this collision? Is it elastic?c. What type of collision is it?

The Moon's craters are remnants of meteorite collisions. Suppose a fairly large asteroid that has a mass of 5.06 ✕ 1012 kg (about a kilometer across) strikes the Moon at a speed of 14.8 km/s. A. How much kinetic energy (in J) is lost in the collision? Such an event may have been observed by medieval English monks who reported observing a red glow and subsequent haze about the Moon. B. In October 2009, NASA crashed a rocket into the Moon, and analyzed the plume produced by the impact. (Significant amounts of water were detected.) Answer part (a) and (b) for this real-life experiment. The mass of the rocket was 2000 kg and its speed upon impact was 9000 km/h. speed of recoin (in m/s) loss of kinetic energy (in J)

A pitcher throws a 0.60 kg ball of clay at a 2.0 kg block of wood. The clay sticks to the wood on impact, and their joint velocity afterward is 2.0 m/s. What was the original speed of the clay (in m/s)?

A 1600 kg car traveling at 20.0 m/s collides with a 2200 kg car travelling in the same direction 14.0 m/s. The two cars stick, together after the collision. a. What is the speed of the two cars after the collision? b. How much energy is lost in the collision?
