What is angular velocity of bike wheel at end of this time

Reference no: EM13488155

A girl jumps on bike and exerts torque of 25.0 N-m perpendicular to the pedal. Moment of inertia of bike wheel is I = 0.045kg-m^2. The ground exerts a torque of 20.0 N-m in opposite direction of torque girl exerts on bike pedal. What is net torque on bike wheel? What is angular acceleration of "a" of bike wheel? The bike is pedaled for 4.0 secs at this rate. What is angular velocity of bike wheel at end of this time?
