Activity 5. Radian and Rotational Problems Directions: Solve the problem and show all pertinent solution. 1. A computer's hard drive spins at 7200 RPM. What is the angular velocity in rad/s? What is the velocity in m/s of the hard drive at a radius of 0.0889 m? 2. A record player has a velocity of 33.33 RPM. How fast is the record spinning in m/s at a distance of 0.085 m from the center? 'ba 3. A race car travels in a circular track of radius 200 m. If the car moves with a constant speed of 80 m/s, find (a) its angular velocity and (b) its tangential acceleration
