A ball leaves the track at `B` which is at `3m` height from bottom most point of the track. The ball further rises upto `4m` height from the bottom most point before falling down. Find `h` (in `m`), if the track at `B` makes an angle `30^@` with horizontal.

A ball falls from a height of 10 m. On rebounding, it loses 30% energy. The ball goes upto a height of

An elastic balls falls from a height of 10 m . If lose 80 % of its total energy due to impact . The ball will now rise to a height of ?

A particle (m = 2 kg) slides down a smooth track AOC starting from rest at point A (height = 5m). After reaching point C (height =1m), the particle continues to move freely in air as a projectile. The particle velocity at point C is at angle 60^(@) with the horizontal. The maximum height attained by particle after leaving point C is _____(in m).

A ball rolls down an inclined trck 2 m long in 4s. Find speed of the ball at the bottom of the track.

A ball is thrown horizontally from the top of a tower 40 m high. The ball strikes the ground at a point 80 m from the bottom of the tower. Find the angle that the velocity vector makes with the horizontal just before the ball hits the gound.

A body of mass 10kg is at height of 10m at point A as shown on a smooth track. Find speed at B.

A ball thrown down the incline strikes at a point on the incline 25m below the horizontal as shown in the figure. If the ball rises to a maximum height of 20m above the point of projection, the angle of projection alpha (with horizontal x axis) is
