Question

A top fuel dragster is designed to go from 0 to 100 miles per hour in a mere 0.8
seconds. Calculate its acceleration. Show your work and include units.

Answer 1

Answer:

Acceleration, $a=55.88\ m/s^2$

Explanation:

It is given that, A top fuel dragster is designed to go from 0 to 100 miles per hour in a mere 0.8.

Initial velocity, u = 0

Final velocity, v = 100 mph

1 mph = 0.44704 m/s

100 mph = 44.704 m/s

Time, t = 0.8 s

We need to find its acceleration. Rate of change of velocity equals acceleration.

$a=\dfrac{v-u}{t}\\\\a=\dfrac{44.704-0}{0.8}\\\\a=55.88\ m/s^2$

So, the acceleration is $55.88\ m/s^2$
