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?

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

So, the acceleration of the rocket is .

what was the acceleration of the 2 kg cart?

⇒ 16.0 cm/s2

what was the acceleration of the 4 kg cart?

⇒ 8.1 cm/s2

what was the acceleration of the 6 kg cart?

⇒ 5.3 cm/s2
