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 intervl t= 1 s to t= 4 is
Explanation:
Avg velocity = displacement/time
t = 1s
t =4s
a=2
S= 2 + a(3)
V = v² + 2as
64 = 4 +2(2)
15 =s
Avg velocity =15/3
=5
