Answer:
2 m/s²
Explanation:
Given that
mass of the car, m = 1200 kg
Initial velocity of the car, u = 0 m/s
Distance covered, s = 450 m
Time taken, t = 15 s
Final velocity of the car, v = s/t = 30 m/s
there are four equations of motion. In this question, we will be attempting to solve it using the first equation of motion to solve this question
v = u + at, where
v = final velocity
u = initial velocity
a = acceleration
t = time taken
v = u + at
30 = 0 + 15a
30 = 15a
a = 30/15
a = 2 m/s
