If the displacement of an object is proportional to square of time, then the object moves with

Velocity of a body at rest is always

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 $$ms^{-2}.$$

A ball is thrown vertically upwards with a speed of $$30\ ms^{-1}$$. The equation for velocity is  (Take g= $$10\ ms^{-2}$$)

The velocity of a body can change

Physical quantity corresponding to the rate of change of displacement is

If two masses $$ m_1,\ m_2$$ are thrown vertically upwords with the same velocity, what is the difference in the maximum height gained by them? ($$ m_1 > m_2$$)

The expression for the velocity when a body dropped from a height reaches the ground is

Unit for the rate of change of velocity is

The displacement of a body which starts from rest, and moving with an acceleration of  $$1\ ms^{-2}$$ at the end of $$5\ s$$ in m is:
