Question

The odometer reading of vehicle are 3650 and 3970 and the vehicle moving with initial velocity and final velocity are 20m/s and 40m/s respectively.find the acceleration produced?​

Answer 1

Given,

Time (t)=10 seconds

Accelerartion (a)=2.5 m/s

2

We know v=u+at

⇒40m/s=u+2.5×10 m/s

2

⇒40m/s=u+25 m/s

⇒u=(40−25) m/s

u=15m/s

∴ initial velocity of the car =15 m/s
