If the car is intially at rest, what is the distance traveled during the acceleration?
In 1970, a rocket-powered car called Blue Flame achieved a maximum speed of 278 m/s. Suppose the mafnitude of the car's constant acceleration is 556 m/s^2. If the car is initally at rest, what is the distance traveled during the acceleration?
This can be solved using one of the kinematic equations of motion. We have the following information:
v = final speed = 278 m/s
a = acceleration = 556 m/s²
u = initial speed = 0 m/s
d = distance = ?
v² = u² + 2ad. Since u=0, this reduces to v² = 2ad and rearranges to d = v²/2a = 278²/2*556 = 69.5 m.
