Question

This is a physics question about acceleration, I'm a Sophmore btw

"Determine the amount of time it takes for a car to accelerate forward at a rate of 7.00 m/s^2 if it starts from rest and reaches a final speed of 30.0 m/s."

I was having trouble figuring out the time if anyone can help that'd be lovely!!

Answer 1

4.29 s

Step-by-step explanation:

Given:

v₀ = 0 m/s

v = 30.0 m/s

a = 7.00 m/s²

Find: t

v = at + v₀

30.0 m/s = (7.00 m/s²) t + 0 m/s

t = 4.29 s
