Question

I've worked this one out a few times in got the same calculation. Even my tutor for the same calculation. The only problem I'm having issues with this early in the semester.

In 1898, the world land speed record was set by Gaston Chasseloup-Laubat driving a car named Jeantaud. His speed was 39.24 mph (63.15 km/h), much lower than the limit on our interstate highways today. Repeat the calculations of Example 2.7 (assume the car accelerates for 6 miles to get up to speed, is then timed for a one-mile distance, and accelerates for another 6 miles to come to a stop) for the Jeantaud car. (Assume the car moves in the +x direction.)

(a) Find the acceleration for the first 6 miles.

Hypothesized Acceleration: 0.01593 m/s^2

Explanation / Answer

v = 63.15 km / h

v = 63.15*5/18 = 17.5417 m/s

Distance (S) = 6 miles = 9656.06 m

v^2 = u^2 + 2aS

a = 17.5417^2 / 2*9656.06

a = 0.01593 m/s^2
