Question

An object is moving with 40m/s .if it obtains an uniform acceleration 10m/s2 in 7s ,find the final velocity .with equation, step

Answer 1

Here,initial velocity (u) = 40 m/s
Acceleration (a) = 10 m/s^2
The time (t)=7sec
Final velocity (v)=?
Therefore according to the relation v= u + at
We get v =110m/s

Answer 2

u=40m/s

a=10m/s²

t=7s

v=?

By v=u+at,we get-----

v=40+10×7

v=40+70

v=110m/s

Thys,final velocity is 110m/s
