A particle starts from rest  with acceleration $$ 2\ m/s^2 $$, The distance moved by the particle in 5 sec is:

A train starting from a railway station and moving with uniform acceleration attains a speed $$40km\ h^{-1}$$ in $$10$$ minutes. Find its acceleration.

A body starting from rest moving with uniform acceleration has a displacement of $$16 \ m$$ in first $$4 \ s$$ and $$9 \ m$$ in first $$3 \ s$$. The acceleration of the body is  

A stone falls from a balloon that is descending  at a uniform rate of $$12\, ms^{-1}$$. The displacement of the stone from the point of release after 10 sec is :-

$$2nd$$ equation of motion $$(s=ut + \dfrac{1}{2}at^2)$$ can be derived graphically form $$v-t$$ graph by finding

A particle is released from rest from a tower of height 3h.The ratio of times to fall equal height h,i.e., t$$_{1}$$: t$$_{2}$$ :t$$_{3}$$ is 

Calculate the speed of the body as if moves from: B to C.

A helicopter is flying at a height of $$500m$$. If all of sudden its engines stop working, the helicopter will fall on the earth in __ seconds?

The displacement - time graph of a particle moving in a straight line is shown in the figure. Then

A ball is dropped from a balloon moving upwards with velocity $$10\ m/s$$ at a height of $$20\ m$$ from the ground. The distance traveled by the ball before reaching the ground is: (Take $$g=10\ m/s^2)$$
