A 0.20 kg arrow with a velocity of 10 m/s to the west strikes and pierces the center of a 6 kg target. a.What is the final velocity of the combined mass? b.What is the decrease in kinetic energy during the collision

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 bullet of mass 18.4 grams is fired with a speed of 341 meters per second toward a wood block of mass 249 grams initially at rest on a very smooth surface. a. What is the change in momentum of the bullet if it becomes embedded in the block? b. What is the change in momentum of the bullet if it ricochets in the opposite direction with a speed of 330 meters per second?

1. The dynamics TAs want to do an experiment with bowling balls to figure out their velocity after colliding. Bowling ball A has a mass of 3kg and is moving at 8 m/s to the right and it makes a direct collision with bowling ball B, which has a mass of 2 kg and is moving 4 m/s to the left. If e=0.7, what is the velocity and direction of each bowling ball just after the collision. You can neglect the size of the bowling balls. [Ans. To Check: va=0.16m/s←] 8 m/s 4m/s B

Dr. Knotts's kids are chasing each other through the yard. Arlo is in the lead and Greyson is chasing him from behind. Arlo has a mass of 13.1 kg and is running at 1.06 m S After they run into each other, Greyson has a velocity of 1.14 19.6 kg and is running in the same direction at 1.44 How fast is Arlo moving just after they collide? VArlo m S What is the total kinetic energy of the system before the collision? KEinitial J = What is the total kinetic energy of the system after the collision? KEfinal J = Is this collision considered eleastic, inelastic, or both? O Inelastic Both Elastic m S m S in the same direction he was already moving. I I Greyson has a mass of

A bullet of mass 20 g is fired into ballistic pendulum of mass 3 kg initially at rest. The bullet exists from the other side of the ballistic pendulum with speed of 100 m/s while the ballistic pendulumswing throw an arc reaching a maximum height of 20.41 cm. a. calculate the speed of the ballistic pendulum just after the collision. b. calculate the speed of the ballet before it hits the ballisic pendulum. c. calculate the lost kinetic energy in this collision.
