a block of mass 10 kg is kept on the top of an inclined plane having angle of inclination 60 degree and coefficient of friction 0.1 will the body slide down this plane or remain stationary.if it does slide down then with what acceleration does it move down.it the length of the inclined plane is 5 m, then find the time taken by it to reach at the bottom. also find the net work done during the displacement of the block. what is the work done on the block only due the friction force alone?
