If acceleration is constant and non-zero, the velocity-time graph is:
The displacement 's' of a particle at time 't' is given by s = 4t^2. The acceleration is:
A car travels from A to B at 20 km/h and from B to A at 30 km/h. The average speed for the whole journey is:
The initial velocity of a body is u. It stops after a time t. The retardation is:
A body starting from rest moves with a uniform acceleration of 2 m/s^2 for 5 seconds. The distance covered in the 5th second is:
Two balls A and B of masses 1kg and 2kg are dropped from the same height. The ratio of their times to reach the ground is:
A stone is dropped from a rising balloon moving up at 10 m/s. If the balloon is at 40m height, the time taken by stone to hit ground is (g=10):
A body covers 1/3 of its journey with speed 'u', next 1/3 with 'v' and last 1/3 with 'w'. The average speed is:
The displacement of a particle is given by x = (t-2)^2. When is the velocity zero?
A car moving at 40 km/h can be stopped by brakes in 2m. If the same car moves at 80 km/h, the stopping distance is:

A particle moves along a circle of radius R. In half a revolution, what is the ratio of distance to displacement?
Two bodies A and B are thrown with velocities u and 2u. The ratio of maximum heights attained is:
A body moves with constant acceleration 'a'. If its velocity at two points is 'u' and 'v', its velocity at the midpoint of the path is:
The acceleration of a particle is increasing linearly with time t as bt. The velocity of particle at time t will be (starting from rest):
What is the displacement of a particle moving in a circle of radius r after it has turned through an angle theta?
A car is moving with velocity V. If the brakes provide a retardation 'a', the time required to stop is:
