Question

An object has an average acceleration of +6.07 m/s2 for 0.250 s . At the end of this time the object's velocity is +9.64 m/s .

What was the object's initial velocity?

Answer 1

Step-by-step explanation:

From the question we are given;

Acceleration a = 6.07m/s²

Time t= 0.25s

Final velocity v = 9.64m/s

Required

Initial velocity u

Using the equation of motion

v = u+at

9.64 = u+(6.07)(0.25)

9.64 = u+1.5175

u = 9.64-1.5175

u = 8.1225m/s

Hence the object's initial velocity is 8.1225m/s
