Question

A block of mass 2 kg is placed on a plane surface. It's inclination from the horizontal may be changed the block is just at the verge of sliding when the inclination of the plane is 30°. Calculate the acceleration with which the Block with slide down when the inclination of the plane is 45°.​

Answer 1

Answer:

Given, m = 2kg θ = 300 μ = 0.5 g = 10m/s2 The contact force is Fc is the resultant of frictional force and normal force.From the free body diagram,Normal ... ·
