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

`a=242.62\ m/s^2`

Step-by-step 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=(444\ m/s)/(1.83\ s)\\\\a=242.62\ m/s^2`

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