A rocket is fired vertically upwards with a net acceleration of `4 m//s^2` and initial velocity zero. After `5s` its fuel is finished and it decelerates with g. At the highest point its velocity becomes zero. Then, it accelerates downwards with acceleration g and return back to ground. Plot velocity-time and displacement -time graphs for the complete journey. Take `g=10m//s^2.`

A rocket is fired upwards vertically with a net acceleration of 4"m/s"^2 and initial velocity zero. After 5 seconds its fuel is finished and it decelerates with g. At the highest point its velocity becomes zero. There after it accelerates downwards with acceleration g and return back to ground. (i) Plot velocity – time graph for complete journey (ii) Displacement-time graph for the complete journey. (Take g = 10 m//s^2 .)

A rocket is fired vertically upwards and moves with net acceleration of 10 m//s^(2) . After 1 min the fuel is exhausted. The time taken by it to reach the highest point after the fuel is exhausted will be:

If acceleration a(t) = 3t^(2) and initial velocity u=0 m/s , then the velocity of the particle after time t=4 s

If a ball is thrown vertically upwards with a velocity of 40m//s , then velocity of the ball after 2s will be (g = 10m//s^(2))

If a ball is thrown vertically upwards with a velocity of 40m//s , then velocity of the ball after 2s will be (g = 10m//s^(2))

A body moves with a uniform acceleration and its initial velocity is 5 m/s . After 10 seconds, its velocity becomes 25 m/s . Find the acceleration of the body.
