A 6.02-kg object passes through the origin at time t = 0 such that its x component of velocity is 4.55 m/s and its y component of velocity is -3.21 m/s.
(a) What is the kinetic energy of the object at this time?
(b) At a later time t = 2.00 s, the particle is located at x = 8.50 m and y = 5.00 m. What constant force acted on the object during this time interval?
(c) What is the speed of the particle at t = 2.00 s?
