What is the average velocity of the car over the first 0.25m? m/s what is the average velocity of the car over the second 0.25m? m/s

First Car Avg: Velocity=0.11 m/s

Second Car Avg: Velocity=0.28 m/s

Explanation:

Data

D1  (First Car Displacement)=0.25m

T1 (First Car total time taken)=2.23s

D2 (Second Car Displacement)=0.25m

T2(Second Car time taken)=3.13-2.23=0.9s

Avg: Velocity1=?

Avg: Velocity2=?

Solution

Avg: Velocity1=D1/T1

Avg: Velocity1=0.25/2.23

Avg: Velocity1=0.11 m/s

Avg: Velocity2=D2/T2

Avg: Velocity2=0.25/0.9

Avg: Velocity2=0.28 m/s
