An elevator cable winds on a drum of radius 90.0 cm that is connected to a motor.
a)If the elevator is moving down at 0.50 m/s, what is the angular speed of the drum? (2)
b)If the elevator moves down 6.0 m, how many revolutions has the drum made? (2)
c)What is the angular displacement of the drum when the elevator moves down 6.0 m. (2)
d)What is the radial acceleration of a point on a drum located at a distance of 90.0 cm from the axis of rotation, when the elevator is moving down at 0.5 m/s? (2)
e)What is the net force acing on the elevator when the elevator is ascending at a constant speed of 0.50 m/s? (2)
