Question

A particle moves from 5 m\s to 8 m\s in 4 second. find the acceleration.

Answer 1

given
u=5
v=8
t=4
a=v-u/t
a=8-5/4
a=3/4
a=0.7m/s2

Answer 2

heya friend 

initial velocity {U} = 5 m/s 

final velocity {V} = 8m/s 

time = 4s

acceleration = v-u/t = 8-5/4 = 3/4 m/s square = 0.75 m/s square
