Question

A car starting at rest attains a speed of 6.2 m/s in 12 s. What is the car's acceleration?

Answer 1

Explanation:

The car changes its velocity with the following equation:

$v = v_{0} + at$, where v is the velocity at time t and v0 is the initial velocity(when t = 0)

assuming v0 = 0, you plug in the values 6.2 and 12 into that equation(see image)
