Question

The velocity changes from 45m/s to 60m/s in Three seconds. What is its
acceleration?

Answer 1

5 m/s²

Step-by-step explanation:

Intial velocity (u) = 45 m/s

Final velocity (v) = 60 m/s

Time (t) = 3 s

To find

Acceleration (a)

Formula

a = (v - u)/t

a = (60 - 45)/3

= 15/3

a = 5 m/s²

Hence

The acceleration is 5 m/s².
