Question

Two blocks are connected by a string, as shown in the figure. The smooth inclined surface makes an angle of 42 ? with the horizontal, and the block on the incline has a mass of 6.7 kg.

Find the mass of the hanging block that will cause the system to be in equilibrium. (The pulley is assumed to be ideal.)

Explanation / Answer

by force balancing

6.7 *9.8*sin42=m*9.8

=>m=4.48 kg
