Two masses, m, = 2.16 kg and m, = 9.71 kg are on a horizontal frictionless surface and they are connected together with a rope as shown in the figure. The rope will snap if the tension in it exceeds 50.0 N. What is the maximum value of the force F which can be applied? Submit Answer Tries 0/10 What is the acceleration of the whole system, when this maximum force is applied? 4.212m/s 2 Submit Answer Incorrect. Tries 1/10 Previous Tries

Newtons Third Law: In the figure provided, a 220. kg crate, to the right of the pulley, is released from rest and begins to fall to the ground. If the mass on the left is m = 55.0 kg, what is the magnitude of the tension of the rope attached to the 220. kg crate? Assume the rope and pulley are massless. 862 N 2.16×103 N 431 N 539 N

When rapidly turning a corner on a flat road, a cyclist leans into the center of the turn.
