Question

a motorcycle takes 8 sec to increase its velocity from 10m/s to 30m/s.what is its average acceleration?

Answer 1

u = 10 m/s
v = 30 m/s
t = 8s
a = (v-u)/t = (30-10)/8 = 20/8 = 2.5 m/s²
∴average acceleration is 2.5 m/s²

Answer 2

Answer: 2.5 m/s²

Explanation:

v=u + at

a=(v-u)/t

a=(30 - 10)/8 m/s²

a=20/8 m/s²

a=2.5 m/s²
