Question 1 A cooling fan is turned off when it is running at 600 rev/min. It turns 1100 revolutions before it comes to a stop. What was the fan's angular acceleration, assumed constant? Answer is a negative number. S Question 2 5 pts A softball player swings a bat, accelerating it from rest to 3.2 rev/s in a time of 0.215. Approximate the bat as a 0.9 kg uniform rod of length 0.91m, and compute the torque the player applies to one end of it. A 2.95kg uniform cylindrical grinding wheel of radius 32cm is rotating at 1400 rpm. How much torque is required to stop it in 55? S
