Anyone able to help? At 11:55 p. m., Thomas ties a weight to the minute hand of a clock. The clockwise torque applied by the weight (i. e. the force it applies on the clock's hand to move clockwise) varies in a periodic way that can be modeled by a trigonometric function.
The torque peaks 15 minutes after each whole hour, when the minute hand is pointing directly to the right, at 3 Nm (Newton metre, the SI unit for torque). The minimum torque of−3 Nm occurs 15 minutes before each whole hour, when the minute hand is pointing directly to the left.
Find the formula of the trigonometric function that models the torque τ applied by the weight t minutes after Thomas attached the weight. Define the function using radians.
