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 = 0.6 kilogram and θ = 45°? if necessary, round the answer to the nearest tenth of a newton.
