Question

6. One minute after takeoff, a rocket carrying the space shuttle into outer space reaches a speed of 447 m/s.

What was the average acceleration of the rocket during that initial minute?

Answer 1

acceleration of the rocket is given as

`a = 7.45 m/s^2`

Step-by-step explanation:

As we know that rocket starts from rest and then reach to final speed of 447 m/s after t = 1 min

so we have

`v_i = 0`

`v_f = 447 m/s`

`t = 1 min = 60 s`

so we have

`a = (v_f - v_i)/(t)`

`a = (447 - 0)/(60)`

`a = 7.45 m/s^2`
