QUESTION:

Problem 8PE

What is the deceleration of the rocket sled if it comes to rest in 1.1 s from a speed of 1000 km/h? (Such deceleration caused one test subject to black out and have temporary blindness.)

ANSWER:

Step 1 of 4:

The deceleration is the process of stopping a body which is already in motion. This is also called as negative acceleration or retardation. It takes the symbol and unit of acceleration. Here in our problem, the initial speed of a rocket sled is given. We need to find the deceleration produced in the rocket to stop it in 1.1 s.

        The initial speed of the sled  

        The time taken to come to rest
