A race car travels northward on a straight, level track at a constant speed travels 0.745 km in 22.0 s. The return trip over the same track is made in 27.0 s.
(a) What is the average velocity of the car in m/s for the first leg of the run?
m/s

(b) What is the average velocity for the total trip?
m/s

  • physics - ,

    Distance = velocity x time
    .745 = velocity x 22

    divide both sides by 22 to get the velocity for the first leg.

    .745 = velocity x 27

    do the same to get the velocity for the second leg.

    to get the average: add the two velocities and divide by two.
