Answer 1

Answer:

Speed=100m/s; Velocity=0m/s.

Step-by-step explanation:

Speed=distance/time

Distance=circumference of the circle

circumference=2πr

2×3.14×100=314×2=628m

Speed=628/6.28

= 62800/628=100

Therefore, Speed=100m/s

Velocity= displacement/time

Note: displacement becomes 0 because the car comes to the initial point after every lap.

=0/628=0

Answer 2

Answer:

10ms-1

Step-by-step explanation:

Radius of lap = 100m

circumference =2rR=200r=628m

time taken to cover one lap=62.8s

average speed =628/62.8=10ms-1
