Question

show work

Block A has a mass of 100.0 kg and is placed at the top of the 2.0-m high ramp. Block B has a mass of 50.0 kg. The system is initially at rest. The ramp is inclined 30.00 with respect to the floor. The coefficient of kinetic friction between block A and the ramp is 0.2. An external force of 400.0 N is applied on Block A. a) Use Newton's Second Law of motion to determine the acceleration of the system. Show all work. b) When block A reaches the end of the ramp, the external force is removed, the cable breaks and block A slides 0.5 m along a frictionless horizontal surface and collides elastically into block C which was initially at rest. The velocity of Block A has the same velocity on the frictionless surface as it does at the bottom of the ramp. The velocity of block A after the collision is zero. The velocity of block C after the collision is -0.6 m/s. Determine the mass of block C. в
