A motorcycle starts from a standstill. In 15 seconds, it reaches a velocity of 20 m/s. What is the motorcycle's average acceleration?

Asked by Nicolle137

Answer (2)

Average acceleration = (change in speed) / (time for the change)
Average acceleration = (20m/s) / (15 sec) = (1 and 1/3) m/s²

The average acceleration of the motorcycle is approximately 1.33 m/s², calculated by dividing the change in velocity (20 m/s) by the time taken (15 s). This means the motorcycle speeds up by about 1.33 m/s each second. The initial velocity is zero since it starts from a standstill.
