A race car traveling northward on a straight, level track at a constant speed travels 0.760 km in 21.0 s. The return trip over the
same track is made in 26.0 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 (in m/s) for the total trip?
m/s

The average velocity of the car in m/s for the first leg is 36.2 m/s and the average velocity (in m/s) for the total trip is 7 m/s

What is Speed and Velocity ?

Speed is the distance travelled per time taken. The S.I unit is m/s. The average speed is the ratio of the total distance travelled to the to time taken. While velocity is the distance travelled in a specific direction per time taken

Given that a race car traveling northward on a straight, level track at a constant speed travels 0.760 km in 21.0 s. The return trip over the same track is made in 26.0 s.

(a) The average velocity of the car in m/s for the first leg of the run will be

Velocity = (0.760 x 1000)/ 21

Velocity = 760 / 21

Velocity = 36.2 m/s

(b) The average velocity (in m/s) for the total trip will be

36.2 - (0.760 x 1000)/ 26

36.2 - (760) / 26

36.2 - 29.2

7 m/s

Therefore, the average velocity of the car in m/s for the first leg is 36.2 m/s and the average velocity (in m/s) for the total trip is 7 m/s
