The blades in a blender rotate at a rate of 4.250 E+3 rpm. When the motor is turned off during operation, the blades slow to rest in 4.75 s. What is the angular acceleration (a positive number in rad/s2) as the blades slow down? (Could you explain how I convert an equation that are listed as E + a number and what equation I can use to find angular acceleration. Thank you.)
