: 24/7 storing D Question 1 10 pts rary A grindstone spinning at the rate of 14.5 rev/s has what approximate angular speed in rad/s? D Question 2 10 pts Computation An electric grinder is spinning CCW at 30 rev/s when the power is turned off and the grinder slows at a steady rate, taking 84 s to stop rotating. Taking CCW rotations as positive, what was the grinder's angular acceleration while slowing to a stop? [Tip: Be careful with units.] O = rad/s2 Record your numerical answer below, assuming three significant figures. Remember to include a "-" as necessary. D Question 3 10 pts A point on the rim of a 0.39-m-radius rotating disk has a centripetal acceleration of 2.93 m/s2. What is the angular speed, in rad/s, of a point 0.14 m from the center of the disk? D Question 4 10 pts A ventilation fan has blades 0.24 m long rotating at 35 rpm. What is the centripetal acceleration of a point on the outer tip of a blade
