What is the acceleration of the race car that moves at constant velocity of 300 km/hr ?

If a bus travelling at $$20\ m/s$$ is subject to a steady deceleration of $$5\ m/s^{2}$$, how long will it take to come rest?

The velocity of a body moving with a uniform acceleration of $$2 m/sec^2$$ is $$ 10 m/sec$$. Its velocity after an interval of 4 sec is 

A heavy stone is thrown from a cliff of height $$h$$ with speed $$v$$. The stone will hit the ground with maximum speed if it is thrown:

The rate of change of velocity is:

Ball A is dropped freely while another ball B is thrown vertically downward with an initial velocity $$v$$ from the same point simultaneously. After $$t\ seconds$$ they are separated by a distance of: (Given that $$t$$ is less than the time required by ball B to reach the ground.) 

A body starting with a velocity $$v$$ returns to its initial position after $$t$$ second with the same speed along the same line. Acceleration of the particle is :

A body dropped from the top of a tower reaches the ground in $$4\;s$$. Height of the tower is (Take $$g=9.8 \ m/s^2$$):

A ball dropped freely takes $$0.2\;s$$ to travel the last $$6\;m$$ distance before hitting the ground. Total time of fall is $$(g=10\;ms^{-2})$$:
