Consider a 4.6 kilogram object moves from the origin always to the right (call that x-axis). Its speed increases uniformly (means constant acceleration) from zero to 0.667 metres/sec.


1.Describe how its velocity changes: initial, final and whether it changes uniformly.
2.The object takes 2.8 seconds to reach to that final speed. Describe its acceleration vector.
3.Write an equation for its speed in terms of time.
4.Find an equation for its kinetic energy as a function of time.
5.Use Newton's second law: F=(mass)a to calculate the total force acting on the object. Remember that force and acceleration are vectors.
