A block is placed at the end of a frictionless ramp and is pulled up the ramp by 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 3.00 meters long and has an angle of incline of 20.0° with the horizontal. The mass of the block is 3.80 kg, while the mass of the ball is 1.70 kg.
A) Draw the free-body diagram for ball and the block in this problem.
B) Determine the magnitude and direction of the acceleration of the system.
