$Assertion$ : The two bodies of masses $M$ and $m$ $(M > m)$ are allowed to fall from the same height if the air resistance for each be the same then both the bodies will reach the earth simultaneously.

$Reason$ : For same air resistance, acceleration of both the bodies will be same

Four marbles are dropped from the top of a tower one after the other with an interval of one second. The first one reaches the ground after $4$ seconds. When the first one reaches the ground the distances between the first and second, the second and third and the third and forth will be respectively

A body falls freely from the top of a tower. It covers $36\%$ of the total height in the last second before striking the ground level. The height of the tower is……..$m$

A particle is projected up with an initial velocity of $80\;ft/\sec $. The ball will be at a height of $96\;ft$ from the ground after

A rocket is fired vertically up from the ground with a resultant vertical acceleration of $10\  m/s^2$. The fuel is finished in $1\  minute$ and it continues to move up.$(a)$ the maximum height reached.$(b)$ After how much time from then will the maximum height be reached (Take $g = 10\  m/s^2$)
