The acceleration of the rider initially going at a speed of 15m/s but comes to a stop at 50m is 2.25m/s².

How to calculate acceleration?

The acceleration of a moving body can be calculated by using the following formula:

v² = u² + 2as

Where;

  • v = final speed
  • u = initial speed
  • a = acceleration
  • s = distance

15² = 0² + 2×a×50

225 = 0 + 100a

a = 225/100

a = 2.25m/s²

Therefore, the acceleration of the rider initially going at a speed of 15m/s but comes to a stop at 50m is 2.25m/s².
