A rocket is fired upward from the earth's surface such that it creates an acceleration of $20\, m/s^2$. If after $5\, s$ its engine is switched off, the maximum height of the rocket  from the earth's surface would be……$m$

A body falling from a high Minaret travels $40$ meters in the last $2$ seconds of its fall to ground. Height of Minaret in meters is (take $g = 10\,m/{s^2}$)

A stone falls from a balloon that is descending at a uniform rate of $12\,\,m/s$. The displacement of the stone from the point of release after $10 \,sec$ is…….$m$

($g = 9.8\,m/{s^2}$)

A Tennis ball is released from a height $h$ and after freely falling on a wooden floor it rebounds and reaches height $\frac{ h }{2} .$ The velocity versus height of the ball during its motion may be represented graphically by 

(graph are drawn schematically and on not to scale)

A stone is dropped into water from a bridge $44.1\,m$ above the water. Another stone is thrown vertically downward $1$ sec later. Both strike the water simultaneously. What was the initial speed of the second stone…….$m/s$
