From a balloon moving upwards with a velocity of $12\,ms^{-1}$, a packet is released when it is at a height of $65\, m$ from the ground. The time taken by it to reach the ground is...........$s$ $(g = 10\,ms^{-1})$,
A cricket bowler releases the ball in two different ways
$(a)$ giving it only horizontal velocity, and
$(b)$ giving it horizontal velocity and a small downward velocity.
The speed $V_s$ at the time of release is the same. Both are released at a height $H$ from the ground. Which one will have greater speed when the ball hits the ground ? Neglect air resistance.

A ball is projected from the ground at an angle of $45^{\circ}$ with the horizontal surface. It reaches a maximum height of $120 m$ and returns to the ground. Upon hitting the ground for the first time, it loses half of its kinetic energy. Immediately after the bounce, the velocity of the ball makes an angle of $30^{\circ}$ with the horizontal surface. The maximum height it reaches after the bounce, in metres, is. . . . .
