Guadalupe has a motorized globe on her desk that has a 0.16 m radius. She turns on the 4.25-watt motor and the globe begins to spin. The globe starts from rest and has a final rotational speed of 0.628 rad/s (1 revolution per 10 seconds). The globe reaches this speed in 25 seconds.

A. What is the angular displacement during the 25-second time interval in radians?

B. What is the linear speed of a point on the globe’s equator?

C. What is the average torque provided by the motor during the 25-second time interval?
