There is a particle with mass m = 2 kg attached to a smooth wire that is positioned horizontally so that the particle can only move freely in the horizontal direction. The particle initially moves with a constant velocity V0, = 7 m/s to the right, which is then pulled by a constant force at an angle that varies with time as shown below. If the function of the angle is θ(t) = 0.2t +0.3, where is calculated in radians and t is in seconds, and the magnitude of the constant force is F = 10 N. then calculate: (Review only for 0.3≤θ≤? ) a.
