Question

A block of mass 1 kg is placed on a rough inclined plane of inclination of 37° . find magnitude and direction of friction . also calculate contact force

Answer 1

the contact force will be mgcos37 since it makes an angle of 37 degrees from the ground here m=1 and g=10 and cos 37 is 4/5
so contact force will be 4×1×10/5 = 8N
also the force of friction will be upwards but along the plane on which the block is placed
