Question

if a body acquires velocity 20m/s in 5seconds,it's acceleration is 2m/s square find initial velocity of the body..

Answer 1

Answer:

The initial velocity of the body is 10 m/s.

Step-by-step explanation:

Final velocity (v) = 20m/s

Time (t) = 5s

Acceleration (a) = 2m/s

Initial velocity (u) = ?

Using the formula of motion $v = u + at$,

20 = u + 10

-u = 10 - 20

-u = -10

u = 10 m/s

Therefore, the initial velocity is 10 m/s.
