v=v0+at=>v0=v-at=34-15•1,3=34-19,5=14,5m/s

Answer:

Initial velocity, u = 14.5 m/s

Step-by-step explanation:

It is given that,

Final velocity of the object, v = 34 m/s

Time, t = 1.3 s

Acceleration of the object,
a=15\ m/s^2

To find,

Initial velocity of the object

Solution,

Let u is the initial velocity of the object. It can be calculated using the first equation of motion as :


v=u+at


u=v-at


u=34-15* 1.3

u = 14.5 m/s

So, the initial velocity of the object is 14.5 m/s.
