Motion in A Str...

Unit of acceleration is

A body initially moving with a velocity of $$5\ ms^{-1}$$ attains a velocity of $$25\ ms^{-1}$$ in $$5\ s$$, find the acceleration of body in $$ms^{-2}.$$

If the velocity of a body does not change, its acceleration is

The velocity of an object increases at a constant rate from $$20 m s^{-1}$$ to $$50 m s^{-1}$$in 10 s. Find the acceleration.

The velocity of a body can change

A bomb is released from a horizontal flying aeroplane .The trajectory of bomb as observed from ground is

Unit for the rate of change of velocity is

A block is released from rest at the top of a friction-less inclined plane 16 m long. It reaches the bottom 4 sec later. A second block is projected up the plane from the bottom. At the instant at which the block is released in such a way that it returns to the bottom simultaneously with the first block. The acceleration of each block on the incline is :

Which of the following is/are true about acceleration

An object is thrown vertically upwards and rises to a height of 10 m. Calculate the velocity with which the object was thrown upwards :
