A body of mass 2 kg moves with an acceleration `3ms^(-2)`. The change in momentum in one second is

A body of mass 3kg moving with a constant acceleration covers a distance of 10m in the 3rd second and lbm in the 4th ssecond respectively. The initial velocity of the body is

A mass of 1 kg is suspended by means of a thread. The system is (i) lifted up with an acceleration of 4.9ms^(2) (ii) lowered with an acceleration of 4.9ms^(-2) . The ratio of tension in the first and second case is

A body is moving with uniform velocity of 8 ms^-1 . When the body just crossed another body, the second one starts and moves with uniform acceleration of 4 ms^-2 . The time after which two bodies meet will be :

A boy of 50 kg is in a lift moving down with an acceleration 9.8ms^(-2) .The apparent weight of the body is (g=9.8ms^(-2))

The distance travelled by a particle starting from rest and moving with an acceleration (4)/(3) ms^-2 , in the third second is.
