A 5.50-kg object is initially moving so that its x-component of velocity is 6.00 m/s and y-component of velocity is -1.90 m/s. (a) What is the kinetic energy of the object at this time? (b) Find the change in kinetic energy of the object it its velocity changes so that its new x-component is 8.50 m/s and its new y-component is 5.00 m/s.
