Question

Find the final velocity of a vehicle if it attains an acceleration of 10sec² in 40 secs when the body started at rest.

Please answer....​

Answer 1

Answer:

Here,

Initial Velocity, u =0m/s

Acceleration,a= 10m/sec ^2

Time =40 sec

Final Velocity,v=?

From First Law of Motion,

v=u+at

v=0+10×40 m/s

v=400 m/s

I hope this helps

Answer 2

Answer:

Given initial velocity =0 (vehicle starts from rest)

Given time= 40 seconds

Given acceleration=10m/sec2

For finding final velocity :-

v=u+at (first law of motion)

v=0+10×40

v=400 m/s
