Motion in A Str...

The rate of change of velocity of an object with respect to time is called ..........

How much time elapses during this interval?

A car of mas sm starts moving so that its velocity varies according to the law $$v = \beta\, \sqrt{s}$$  where $$\beta$$ is a constant, ands is the distance covered. The total  work performed by all the forces which are acting on the car during the first t seconds after the beginning of motion is 

An observer finds the magnitudes of the acceleration of two bodies to be the same. This necessary implies that the two bodies.

A block of mass m is suspended by a light thread from an elevator.The elevator is accelerating upward with uniform acceleration a. The work done by tension on  the block during t seconds is (1 = 0) :

A truck increases its speed from $$10km/h$$ to $$50 km/h$$ in $$20$$ seconds. Its acceleration is:

A car is moving with a uniform velocity of 40 km h$$^{-1}$$ in straight line. Its acceleration after 1 hour is:

The speed of the particle moving along with straight line become half after every next second. The initial speed is $$V_0$$. The total distance travelled by the particle will be

A rocket is launched to travel vertically upward with a constant velocity of 20 m/s. After travelling 35 s the rocket develops a snag and its fuel supply is cut off. The rocket then travels like a free body, the height achieved it is

The dispIacement of a body is given by $$2s\, =\, gt^2$$ where g is a constant. The velocity of the body at any time t is:
