A bullet of mass m = 10 g and velocity 300 m/ s is shot into a block of wood that is firmly attached to the ground. The bullet comes to rest in the wood at a depth of 8.1 cm.
(a) What was the acceleration of the bullet?
(b) How long did it take the bullet to come to rest once it entered the wood?
(c) What was the force exerted by the wood on the bullet?
A blue ball is thrown upward with an initial speed of 22.4 m/s, from a height of 0.5 meters above the ground. 2.7 seconds after the blue ball is thrown, How long after the blue ball is thrown are the two balls
Two balls are simultaneously dropped from a height of 5.0 Part A: How long does it take for the balls to reach the ground? Use 10 for the magnitude of the acceleration due to gravity. Part B: Imagine the ball on the left is given a nonzero initial..
