Question

A body moving with uniform acceleration is having velocity 2m/s at 1 sec and 8m/s at 4 sec. Then average velocity of the particle in that time interval

Answer 1

We need to find accleration

V= u+ at

8= 2+ a4

Therefore a equals 3/2

After this u can find displacement d1 for 1 sec and d2 for 8 sec

Qthen avg velocity equals d2- d1/ 4-1
