**physics**

A stationary bicycle is raised off the ground, and its front wheel (m = 1.3 kg) is rotating at an angular velocity of 14.0 rad/s (see the drawing). The front brake is then applied for 3.0 s, and the wheel slows down to 2.7 rad/s. Assume that all the mass of the wheel is ...

Find the net torque (magnitude and direction) produced by the forces F1 (F1 = 17.3 N) and F2 (F2 = 26.1 N) about the rotational axis shown in the drawing. The forces are acting on a thin rigid rod, and the axis is perpendicular to the page. (x = 0.323 m, y = 1.021 m, = 28.6°)
