Question

3. If the average acceleration of a cheetah is 8 m/s, what will its velocity be after 3 seconds if it is

initially walking at 1 m/s?
a) 22 m/s
b) 23m/s
c) 24 m/s
d) 25 m/s

Answer 1

d) 25 m/s

Step-by-step explanation:

Acceleration is change in velocity over change in time:

a = Δv / Δt

8 m/s² = (v − 1 m/s) / 3s

v = 25 m/s
