Question

A body travels on a straight line with an initial velocity of 2 m/s . If its uniform acceleration is 1 m/s2 , its velocity at the end of 5 seconds is​

Answer 1

Answer:

7m/s

Explanation:

u=2m/s

a=1m/s²

t=5s

v=?

v=u+at

= 2+1×5

= 7m/s

Answer 2

Given :-

Initial velocity = 2 m/s

Acceleration = 1 m/s²

Time = 5 sec

To Find :-

Final velocity

Solution :-

We know that

v = u + at

⇒ v = 2 + 1 × 5

⇒ v = 2 + 5

⇒ v = 7

⇒ v = 7 m/s

∴ Final velocity is 7 m/s
