Question

If the initial velocity of a body is 2m/s and travels a distance of 40m before applying brakes in time 10 sec. Calculate the final velocity

Answer 1

Answer:

please give me Brainliset answer

Explanation:

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
