A ball is thrown vertically upward with some velocity. A constant air resistance acts. If the time of ascent is t1 and that of descent is t2, then A ball is thrown vertically upward with some velocity. A constant air resistance acts. If the time of ascent is t1 and that of descent is t2 [...]

A body is sliding down an inclined plane having coefficient of friction 0.5. If the normal reaction is twice that of the resultant downward force along the incline, the angle between the inclined plane and horizontal is A body is sliding down an inclined plane having coefficient of friction 0.5. If the normal reaction is [...]

The upper half of an inclined plane of inclination 45 degree is perfectly smooth while the lower half is rough. A block starting from rest at the top of the plane will again come to rest at the bottom if the coefficient of friction between the block and the lower half of the plane is [...]

A block is released from the top of an inclined plane of inclination θ. Its velocity at the bottom of plane is v. If it slides down a rough inclined plane of the same inclination , its velocity at bottom is v/2. The coefficient of friction is A block is released from the top of [...]
