Solve the problem. If necessary, round to the nearest tenth.The force acting on a pendulum to bring it to its perpendicular resting point is called the restoring force. The restoring force F, in Newtons, acting on a string pendulum is given by the formula F = mg sin ?where m is the mass in kilograms of the pendulum's bob, g ? 9.8 meters per second per second is the acceleration due to gravity, and ? is angle at which the pendulum is displaced from the perpendicular. What is the value of the restoring force when m = 0.5 kilogram and ? = 45°?

A. 3.4 N
B. 4.2 N
C. 3.5 N
D. 3.3 N
