Question

A biker has a beginning (initial) speed of 3 m/s. After 3 seconds he is now riding at 9 m/s.
What is his acceleration?

Which one is right
• 3 m/s/s

• 2 m/s/s

• 2 s/m/m

• 9 m/s

Answers

The correct answer is 2 m/s/s.

Acceleration is calculated by taking the change in velocity and dividing it by the time taken. In this case, the change in velocity is 6 m/s (9 m/s - 3 m/s) and the time taken is 3 seconds.

Therefore, acceleration = (9 m/s - 3 m/s) / 3 s = 6 m/s / 3 s = 2 m/s/s
