Answer:

Given data;

Initial velocity = 0 m/s

Final velocity =?

Acceleration = 4.6 m/s^2

Times = 10 seconds

Uniform acceleration occurs when the speed of an object changes at a constant rate. The acceleration is the same over time. By relating acceleration to other variables such as speed, time and distance we are able to manipulate data in many ways.


Using the formula;

A = (Vf – Vi) ÷ 2

4.6 = (Vf – 15m/s) ÷ 6s

4.6 × 6 = (Vf – 15m/s) ÷ 6s

27.6 m/s = Vf – 15m/s

27.6 m/s + 15m/s = Vf

Vf = 27.6 m/s + 15m/s

Vf = 42.6 m/s

Answer:

Vf = 42.6 m/s but on edg its 46m/s
