A 1200 kg racing car accelerates from rest at a constant rate and covers a distance of 450 m in 15 s. What is the car's acceleration

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

if you already have the answer to (a), then just work out how many periods there are in 1 minute, and that's the answer to (c).

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.
