Question

An object accelerates from rest to a velocity of 4.0 m/s in 8 seconds. what

was its acceleration

Answer 1

Acceleration (a) = 0.5 mp
`s^(2)`

Step-by-step explanation:

Given,

Object starts from rest, hence the initial velocity of the object is said to be 0

Velocity in the next 8 seconds is 4.0 m/s

u = 0 m/s

v = 4 m/s

t = 8 secs

We know,

a = (v-u)/t

=> a = (4-0)/8

=> a = 4/8 = 0.5 m/
`s^(2)`
