Q1. A block is placed at the end of the frictionless ramp and is pulled up the ramp through a solid ball on the end of a string that passes over a frictionless pulley that does not affect the motion of the block or ball. The ramp is 3.40 meters long and has an angle of incline of 20.0° with the horizontal. The mass of the block is 3.40 kg, while the mass of the ball is 1.40 kg.
A) Draw the free-body diagram for ball and the block in the problem.
B) Establish the magnitude and direction of the acceleration of the system.
Q2. A 35.0-g bullet moving at 445 m/s strikes a 2.4 kg bag of flour that is on ice, at rest. The bullet passes through the bag, leaving at 245 m/s. How fast is the bag moving while the bullet exits?
