A block of mass 1 kg slides down a vertical curved track that is one quadrant of a circle of radius 1m. Its speed ast the the bottom si 2 m//s . The work done by frictional force is :
A skier starts from rest at the top of a ski slope and skis downhill. Find the skier's speed after her elevation decreases by 10m, assuming no work is done by friction or air resistance.
A skier starts from the top of a hill with speed 5m//s and slides down the hill of vertical height 60 m as shown. Neglect friction. Find his speed at the bottom.
A body of mass m is released from the top of a rough inclined plane as shown in figure. If the frictional force be F, then body will reach the bottom with a velocity
A block of mass 1 kg is placed at the point A of a rough track shown in the figure. If slightly pushed towards right, it stops at the point B of the track. The work done by the frictional force on the block during its transit from A to B is
A block f mas 1 kg is placed at the point A of a rough track shown in figure. If slightly pushed towards right, it stos at the point B of the track. Calculate the work done by the frictional force on the block during its transit from A to B.
A block is released from rest from top of a rough curved track as shown in figure. It comes to rest at some point on the horizontal part. If its mass is 200 gm, calculate work by friction is joules
