Question

If a car can accelerate 3.2 m/ s2, how long will it take to speed up from 15 m/s to 22 m/s​

Answer 1

Step-by-step explanation:

Hi

What acceleration =3.2 m/s means is speed is increasing 3.2 m each sec.

So if you start with 15 m/s then in next sec you will have 15+3.2 m/s.

So if you want to reach 22 m/s then ((22-15) /3.2) sec.
