Answer 2

Answer:

Average speed = 15 m/s

Average velocity = 0 m/s

Explanation:

Given:

• Radius of the circular track = 150 metres
• Time taken for completing each lap = 62.8 seconds

To find:

• Average speed of the car
• Average velocity of the car

Average speed = total distance/ total time

total distance = 2πr

total distance = 2×3.14×150

Total distance = 942 metres

Average speed = total distance/total time

Average speed = 942/62.8

Average speed = 15 m/s

The average speed of the car is equal to 15 m/s

average velocity = total displacement/total time

The displacement at the end of one round will be equal to 0 as the car reaches its original place

Average velocity = 0/32.8

Average velocity = 0 m/s

Average speed is 15 m/s and average velocity is 0 m/s
