Jeffrey is on his skateboard and starts skating down a ramp. Ten seconds later he is travelling at

20.0 m/s. What was his acceleration

Answer: 2m/s^2

Explanation:

Velocity of skateboard = 20.0 m/s.

Time taken = Ten seconds (10 s)

Acceleration =?

Recall that acceleration is the change in velocity of a body per unit time.

i. e Acceleration = (velocity / Time)

Acceleration = 20.0m/s ➗ 10 s

Acceleration = 2m/s^2

Thus, Jeffrey acceleration was 2m/s^2
