Solve the problem.

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 sinθ
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 θ is angle at which the pendulum is displaced from the perpendicular. What is the value of the restoring force when m = 0.8 kilogram and θ = 45°? If necessary, round the answer to the nearest tenth of a Newton.
◦ 6.7 N
◦ 5.6 N
◦ 5.3 N
◦ 5.5 N
