If velocity changes from 0 to 10 m/s in 5 s, what is the acceleration?

Explanation:
Acceleration is the rate at which velocity changes. It’s calculated as a = Δv/Δt. Here the velocity goes from 0 to 10 m/s, so Δv = 10 m/s, and the time is 5 s, so Δt = 5 s. That gives a = 10/5 = 2 m/s^2. The positive sign means the object is speeding up.
