Question

Rocket-powered sleds are used to test the human response to acceleration. If a rocket-powered sled is accelerated to a speed of 444 m/s in 1.83 seconds, then what is the acceleration?

Answer 1

Answer:

$a=242.62\ m/s^2$

Explanation:

The rocket-powered sled is accelerated to a speed of 444 m/s in 1.83 seconds.

We need to find the acceleration of the rocket. Initially it was at rest, u = 0

Acceleration = rate of change of velocity

$a=\dfrac{444\ m/s}{1.83\ s}\\\\a=242.62\ m/s^2$

So, the acceleration of the rocket is $242.62\ m/s^2$.
