Answer:

Explanation:
We know that acceleration is change in velocity over time.


v is the final velocity and u is the initial velocity.
Solve for v.
Multiply both sides by t.

Add u to both sides.

Option a) 0.8 m/s² is the correct answer
the acceleration of the motorcycle is 0.8 m/s²
Given the data in the question;
Since the motorcycle stopped then, initial speed u = 0 m/s
final speed v = 12 m/s
time t = 15 s
acceleration = ?
To get our acceleration, we use the first equation of motion.
This equation states that;

so, we simply substitute in our given values

so we find a


Therefore, the acceleration of the motorcycle is 0.8 m/s²
Option a) 0.8 m/s² is the correct answer
