counterclockwise with a con? A discus thrower (arm length 1.1 m) starts from rest and begins to rotate a discus counterclockwise with a constant angular acceleration of +2.2 rad/s^2 k.
(a) How many radians of angle does it take for the discus thrower's angular velocity to reach +5.6 rad/s k?
_____ rads
(b) How long does this take?
_____ seconds
(c) At this time (from part b), please find the following quantities:
the linear speed of the discus:
_____ m/s
the size of the discus's tangential acceleration:
_____ m/s^2
the size of the discus's centripetal acceleration:
_____ m/s^2
the size of the discus's total acceleration:
_____ m/s^2
the angle that the acceleration of the discus makes with its velocity vector:
_____ degrees
(d) During the course of this problem, the angle between the net force on the discus and its velocity _____(Increases, decreases, or stays the same) by an amount of _____ degrees.
