Question

A car starts from an initial velocity of 10 m/s and accelerates at 2.5 m/s^2. How long will it take the car to reach a speed of 40 m/s? How far does the car travel during this time?

Answer 1

300 km

Step-by-step explanation:

Vi 10m/s

Vf = 40m/s

a= 2.5 m/s^2

Vf^2 - Vi^2 = 2as

S = (40^2 -10^2)/(2*2.5) = 300 Km
