Can the direction of the velocity of a body change when it's acceleration is constant.

Show analytically that in S.H.M. the acceleration is zero when the velocity is maximum and that the velocity is zero when acceleration is maximum.

Can a body have zero velocity and finite acceleration?

A body moving with uniform acceleration covers 15m in the third second of its motion and 19.4 m in the fifth sec . If its acceleration and initial velocity.

Starting from the rest , a body P travels with a uniform acceleration of 4m/s^2 and starting from rest from the same point 4s later , a body Q travels with a uniform acceleration of 16m/s_2 in the same direction as P . Find when and where they meet .

Check the correctness of the equation by dimensional analysis. V^2-u^2=2 as Where u = initial velocity of a body V = final velocity of a body a = acceleration of the body s = distance covered

A body starting from rest accelerates uniformly and attains a velocity of 20m/s in 30 seconds. Find its acceleration and the distance it covers in that time

If there is no change in the volume of a wire due to change in it's length on stretching , what would be the poisson's ratio of the material.
