A fox locates its prey, usually a mouse, under the snow by slight sounds the rodents make. The fox then leaps straight into the air and burrows its nose into the snow to catch its next meal. In your calculations ignore the effects of air resistance. 1) If a fox jumps to a height of 81.0 cm. Calculate the speed at which the fox leaves the snow. (Express your answer to three significant figures.)

An observer in the Earth reference frame observes cart A and cart B moving toward each other with the same speed until they collide and come to rest. Consider this event as seen by observer A moving along with cart A. Assume that this observer matches cart A's initial velocity but does not collide with cart B (that is, observer A continues along at the same velocity that cart A had initially).

Part A

Would the observer in the Earth reference frame and observer A obtain the same value for the initial velocity of cart A? (Yes or no)

Part B

Would the observer in the Earth reference frame and observer A obtain the same value for the final velocity of cart B after the collision? (Yes or no)

Part C

Would the observer in the Earth reference frame and observer A obtain the same value for the relative velocity of the two carts after the collision? (Yes or no)

In a ballistics test, a 28-g bullet pierces a sand bag that is 30cm thick. If the initial bullet velocity was 55 m/s and it emerged from the sandbag moving at 18m/s, what was the magnitude of the friction force (assuming it to be constant and the only force present) that the bullet experienced while it traveled through the bag
