Welcome to your Equations of motion
1.
A car moving with a speed of 20m/s can be stopped by applying brakes, after travelling a distance of 2m.The retardation of the car is
2.
A particle ,initially at rest starts moving with a uniform acceleration "a". The ratio of the distance covered by it in first second and first 3s is
3.
A bullet loses 1/20 of its velocity on passing through a plank .The least number of planks required to stop the bullet is
4.
A bus starting with a speed of 12m/s slows down to 6m/s in 3s.The average acceleration of the bus is
5.
If the velocity 'u' of a body moving along a straight line with a constant retardation 'a' is reduced by 75% in time 't', then t is
6.
A body attains a velocity of 25m/s in 2 s with an acceleration of 4m/s2.The displacement of the body is

when a particle is moving with a uniform acceleration then
8.
A particle moves with a uniform velocity ,then
9.
A passenger in a moving train tosses a coin. If the coin falls behind him, the train must be moving with
10.
.The car has managed to drive with uniform velocity of 5m/s for 10minutes,instaneous speed of car at t=500s
