Question

A race car travels northward on a straight, level track at a constant speed travels 0.750km in 17.0s. The return over the same track is made in 22.0s. A) what is the average velocity of the car in m/s for the first leg of the run? B) what is the average velocity for the total trip?

A) what is the average velocity of the car in m/s for the first leg of the run? B) what is the average velocity for the total trip?

Explanation / Answer

A.) Avg velocity = Displacement / time

Avg Velocity = 0.75*10^3 / 17 = 44.11 m/s

B.) Avg velocity = Displacement / time = 0 m/s
