A ball rolls down a ramp for 15 seconds. If the initial velocity of the ball was 0.8 m/sec and the final velocity was 7 m/sec, what was the acceleration of the ball

Respuesta :

MathPhys

Explanation:

Acceleration is the change in velocity over change in time.

a = Δv / Δt

a = (7 m/s − 0.8 m/s) / 15 s

a ≈ 0.413 m/s²
