Question

Two boxes are connected by a light string that passes over a massless, frictionless pulley. One box of mass m_1 rests on a frictionless ramp that rises at an angle theta above the horizontal (see figure). The other box hangs and has mass m_2. The system is released from rest. Call the acceleration of the hanging box "a" in the downwards direction i.e. if a is positive number then m2 accelerates downwards. 1. List all the forces directly acting on m_2 (the hanging box) A the weight of m_1 equal to m_1 g only B tension and the normal force C no forces act on m_2 D The weight of m_2 (equal to m_2g) and tension

Explanation / Answer

Forces acting on m2

1) weight acting vertically downwards

2) Tension acting vertically upwards

so option D) is the correct answer
