Answer:
a) 25 yards per minute
b) linear velocity is the same
c) smaller tire has greater angular velocity
Step-by-step explanation:
a) The linear velocity of the edge of the tire is the same as the linear velocity of the tractor: (100 yd)/(4 min) = 25 yd/min
__
b) All parts of the tractor have the same linear velocity. The outer edge of the smaller tire is moving at the same linear velocity.
__
c) Because the smaller tire must make more turns to cover the same distance in the same time, its angular velocity (turns/time) is greater.
The smaller tire has greater angular velocity.
