Question

A particle starts from rest with constant acceleration. the ratio of space-average velocity to the time average velocity is (1) 1/2 (2) 3/4 (3) 4/3 (4) 3/2

Answer 1

Please find the answer below:

A particle starts from rest with constant acceleration. the ratio of space-average velocity to the time average velocity is 4/3.

Space-average velocity= fvdx/fdx

Time-average velocity= fvdt/fdt

It is given that the initial velocity is zero and it's a case of uniform acceleration.

It can be calculated;

v=at

x= 1/2 at²

v²=2ax.
