Answer:
Acceleration of the car is .
Explanation:
It is given that,
Initial speed of the car, u = 29 m/s
Finally it reaches a speed of, v = 34 m/s
Distance, d = 110 m
We need to find the acceleration of the car as it speed up. It can be calculated using third law of motion as :
So, the acceleration of the car as it speeds up is . Hence, this is the required solution.
Answer:
Option"B" is correct.
Explanation:
when a body move with constant velocity then acceleration is zero.
