A car increases its speed from 20 km/h to 50 km/hr in 10 seconds. Its acceleration is _________.

A racing car accelerates on a straight road from rest to a speed of 50 mis in 25 s. Assuming uniform acceleration of the car throughout, the distance covered in this time will be

A particle accelerates from rest at a constant rate for some time and attains a velocity of 8 m/sec. Afterwards it decelerates with the constant rate and comes to rest. If the total time taken is 4 sec, the distance travelled is

The acceleration of a particle executing SHM at a distance of 3 cm from equilibrium position is 5 cm//s^(2) . Its acceleration at a distance of 2 cm from equilibrium position is

The acceleration of a particle starting from rest moving in a straight line with uniform acceleration is 8m//sec^2 . The time taken by the particle to move the second metre is:

A particle moves along a straight line in such a way that its acceleration is increasing at the rate of 2 m//s^(3) . Its initial acceleration and velocity were zero. Then, the distance which it will cover in the 3^(rd) second (t=2 " to "t =3 " sec") is :

The speed of a particle moving in a circle slows down at a rate of 3 m//sec^(2) . At some instant the magnitude of the total acceleration is 5 m/sec^(2) and the particle's speed is 12 m/sec. The radius of circle will be :
