Answer :
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.
