Answer:
(a). The acceleration is 35.5 m/s².
(b). The distance is 0.214 m.
Explanation:
Given that,
Speed = 3.9 m/s
Time = 0.11 s
We need to calculate the acceleration
Using formula of acceleration

Put the value into the formula


We need to calculate the distance
Using equation of motion

Put the value in the equation


Hence, (a). The acceleration is 35.5 m/s².
(b). The distance is 0.214 m.
