Problem Solving with All Three Kinematics Equations

Question

An object is moving at a velocity of 8.8 m/s. It accelerates to a velocity of 35 m/s over a time

of 6.3 s. What acceleration did it experience?

Answer 1

Your acceleration is the change in velocity over the change in time. Since your velocity changed from 8.8 m/s to 35 m/s, and your change in time is 6.3 s, your acceleration is then (35-8.8)/6.3 = 4.2 m/s²
