The velocity of a particle is towards west at an instant. Its acceleration is not towasrds west, not towards east, not towards north and not towasrds south. Give an example of this type of motion.

A particle has displacement of 12m towards east and 5 m towards north then 6 m vertically upward. The sum of these displacements is-

A particle is moving along a straight line along x-zxis with an initial velocity of 4 m//s towards positive x-axis. A constant acceleration of 1 m//s^(2) towards negative x-axis starts acting on particle at t=0 . Find velocity (in m//s ) of particle at t=2 s .

A particle is moving along a straight line along x-zxis with an initial velocity of 2 m//s towards positive x-axis. A constant acceleration of 0.5 m//s^(2) towards negative x-axis starts acting on particle at t=0 . Find velocity (in m//s ) of particle at t=2 s .

A man moves towards 3m north then 4 m towards east and finally 5 m towards 37^(@) south of west. His displacement from origin is :-

The direction of acceleration of an object performing uniform circular motion is towards the centre.

Two trains leave a railway station at the same time. The first train travels towards west and the second train towards north. The first train travels 5 km/hr faster than the second train. If after two hours they are 50 km. apart, find the average speed of each train.

A particle is moing with a velocity of 10m//s towards east. After 10s its velocity changes to 10m//s towards north. Its average acceleration is:-

A particle moving with constant acceleration of 2m/ s^(2) due west has an initial velocity of 9 m/s due east. Find the distace covered in the fifth second of its motion.

A particle falls towards the earth from inifinity. The velocity with which it reaches the earth is surface is

Read each statement below carefully and state , with reasons , if it is true or false : (a) The net acceleration of a particle in circular motion is always along the radius of the circle towards the centre (b) The velocity vector of a particle at point is always along the tangent to the path of the particle at that point (c ) The acceleration vector of a particle in uniform circular motion averaged over one cycle is a nul vector
