Question

1. What is the final speed of Alex C., who starts from rest and accelerates uniformly at 16.0 meters per second^2 over a distance of 8.0 meters?

Answer 1

Initial Velocity = 0 m/s

Acceleration = a = 16 m/s^2

Final Distance = Xf = 8 m

Initial Distance = Xo = 0 m

Final Velocity ?

Kinematic Equation (constant acceleration)

* Variables are acceleration, position and velocity

2 * a (Xf-Xo) + Vo^2 = Vf^2

2 * 16 * 8 = Vf^2

256 = Vf^2

Vf = 16 m/s
