Motion in a Str...

A body starts from rest. What is the ratio of the distance travelled by the body during the 4th and 3rd second?

The acceleration \'a\' in m/s² of a particle is given by a = 3t² + 2t + 2, where t is the time. If the particle starts out with a velocity u = 2 m/s at t = 0, then the velocity at the end of 2 sec is

For a moving body at any instant of time

What is the relation between displacement, time and acceleration in case of a body having uniform acceleration ?

Two cars A and B at same point initially. If A starts with uniform velocity of 40 m/sec and B starts in the same direction with constant acceleration of 4m/s²

A body travels for 15 sec starting from rest with constant acceleration. If it travels distances S₁, S₂ and S₃ is

A particle travels 10 m first 5 sec and 10 m in next 3 sec. Assuming constant acceleration, what is the distance travelled in next 2 sec?

The motion of a particle is described by the equation u = at . The distance travelled by the particle in the first 4 sec

The position of a particle moving along the x-axis at certain is given below
which of the following describes the motion correctly?

Consider the acceleration, velocity and displacement of a tennis ball it falls to the ground and bounces back. Directions of which of these changes in the process
