I need help with this question

6. 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 6' where m is the mass in kilograms of the pendulum's bob, 3 z 9.8 meters per second per second is the acceleration due to gravity, and 6 is angle at which the pendulum is displaced from the perpendicular. What is the value of the restoring force when m = 0.7 kilograms and t9 = 3 l' ? If necessary, round the answer to the nearest tenth of a Newton
