A toy car travels on a circular track at a constant speed of 0.50ms¯¹. It passes a point on the track at time t = 0 and takes a time of 40 s to travel once around the track. The magnitude of the average velocity of the car between t = 0 and t = 20s is V20- The magnitude of the average velocity of the car between t = 0 and t = 40 s is V40- What are V20 and V40?
A0.32 and 0
B0.32 and 0.32
C0.50 and 0
D0.50 and 0.50
✓ Correct answer
