Question

Given that the hanging block has a mass of 3 kg and the sliding block a mass of 2 kg. The table surface is frictionless and the hanging mass begins 80 cm above the floor. If the hanging mass starts from a state of rest, how fast will it be moving just as it impacts with the floor? Given that the hanging block has a mass of 3 kg and the sliding block a mass of 2 kg.

Explanation / Answer

writing motion equation

3*g - T = 3a

T = 2*a

adding we get, a = 5.88 m/s2

v^2 = u^2 +2as

v^2 = 2*5.88 *0.8

v = 3.06 m/s
