At the time t1 = 0, an object with a mass m = 8.01 kg passes through the origin with a velocity v1 = (5.01î − 2.81ĵ) m/s. At a time t2 = 2.00 s, the object is at the position r = (8.00î + 4.00ĵ) m. Assume that the force acting on the object during the time interval Δt = t2 − t1 is constant and determine the following.
