Question

A car traveling 60 km/h accelerates at the rate of 2m/s^2. How much time is required for the car to reach a speed of 90 km/h?

Answer 1

Answer:

4.16 sec

Explanation:

apply the formula

v= u +at

v-u/a= t

t= 25/6

Answer 2

$\large\boxed{ \fcolorbox{blue}{red}{<strong><em><u>Answ</u></em></strong><strong><em><u>er</u></em></strong><strong><em><u>!</u></em></strong><strong><em><u>.</u></em></strong>}}$

_______________⚡

V = Vo + a*t.

Vo = 60,000m/3600s = 16.7 m/s.

V = 90,000/3600s. = 25 m/s.

a=(v-u)/t

2=(25-16.7)/t

2=(8.30)/t

t=(8.3/2)

t=4.15

hope it's help uh!.
