Question

what will be the velocity of the car in part (a) after 1 minute if it starts from rest ?

Answer 1

Answer:

v = 120m/s

Explanation:

For the car to have accelerated, it means there's a change in velocity. Since the acceleration is uniform, after 1mins(60s), the acceleration still remains the same. Let's calculate the velocity of the car at the end of 60s.

V = u + at.

V = 0 + 2 × 60

V = 120m/s.
