Question

A body is provided with an acceleration of 3m/s2 in 5 seconds, if its final
velocity 25m/s, find the initial velocity

Answer 1

Answer:

10 m/s

Step-by-step explanation:

We have a constant acceleration of 3 m/s², so we can use the equations of motions for constant acceleration.

v = u + a*t

Given, v = 25 m/s, a = 3 m/s², and t = 5 s.

25 m/s = u + 3m/s²*5s

25 m/s = u + 15 m/s

u = 10 m/s.

Thus, initial velocity is 10 m/s in this problem.
