Question

21., A body moving with uniform acceleration is having
velocity 2 m/s and 8 m/s at t = 1 s and t = 4 s
respectively. Then average velocity of particle in the
time interval t = 1 s to t = 4 s is​

Answer 1

A body moving with uniform acceleration is having

velocity 2 m/s and 8 m/s at t = 1 s and t = 4 s

respectively. Then average velocity of particle in the

time interval t = 1 s to t = 4 s is​

Explanation:

Average velocity = displacement/time

u= 2

v = 8

t=3

s= ?

v = u +at

v = v² +2 as

8 = 2+ a(3)

64 = 4+ 2(2) s

Avg velocity = 15/3
