Question

A block of mass m 1 is equal to 2 kg on a smooth incline planes at angle 30 is a connected to a second block of mass m 2 is equal to 3 kg by a cord passing over in a frictionless Pulley as shown in the figure the acceleration of the block is

Answer 1

Explanation:

For the block that is hanging vertically, the equation will be;

20-T=2a.....(1)

For the block in inclined plane the equation will be;

T-3gsin30=3a.....(2)

From both equations ; a= 1m/s^2

And T=18N
