Motion

A body dropped from height 'h' reaches the ground with velocity 'v'. If dropped from '4h', it reaches with:

Identify the vector among the following:

An athlete runs on a circular track of radius R. What is his distance and displacement after 1.5 rounds?

A body is moving with uniform velocity. Which statement is true?

How long will it take for a car to increase its speed from 36 km/h to 72 km/h with an acceleration of 2 m/s^2?

If a ball is thrown vertically up with speed u, the time to reach maximum height is proportional to:

A body starts from rest and moves with uniform acceleration. The ratio of distance covered in 1s, 2s, and 3s is:

Which of the following can have a constant speed but a changing velocity?

A person moves 3m North, then 4m East. The average velocity if the trip takes 5s is:

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:

Which of these describes non-uniform motion?

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:
