2. [0/4 Points] MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Starting from rest, a rider pedals a bicycle such that the angular acceleration of the wheels is a constant 1.30 rad/s². The bicycle wheels are 37.5 cm in radius. DETAILS PREVIOUS ANSWERS (a) What is the magnitude of the bicycle's linear acceleration (in m/s²)? 0.4225 x How is the tangential acceleration of the wheel's edge related to the angular acceleration? Be careful with unit conversion. m/s² (b) What is the angular speed of the wheels (in rad/s) when the linear speed of the bicyclist reaches 10.6 m/s? 34.462 X How is the tangential velocity of the wheel's edge related to the angular velocity? Be careful with unit conversion. rad/s SERCP117.3.OP.007. (c) How many radians have the wheels turned through in that time? 456.81 x What constant acceleration formula relates final angular velocity to initial angular velocity, angular acceleration, and angular displacement? Can you use this to solve for the angular displacement? rad Need Help? (d) How far (in m) has the bicycle traveled in that time? 148.4623 X How is the arc length (which is equal to the linear distance) related to the angular displacement? Be careful with unit conversion. m Read It Need Help? 3. [-/2 Points] DETAILS SERCP11 7.3.P.014. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER An electric motor rotating a workshop grinding wheel at a rate of 1.41 x 10² rev/min is switched off. Assume the wheel has a constant negative angular acceleration of magnitude 3.30 rad/s². (a) How long does it take for the grinding wheel to stop? (b) Through how many radians has the wheel turned during the interval found in (a)? rad Read It
