Ms. Weaver would like to join Elon Musk and travel the stars. The rocket needs 90 seconds to reach a top speed of 1000m/s. What would Ms. Weaver and Elon Musk's acceleration be on the rocket?

Answer:

The acceleration of Ms. Weaver and Elon Musk's acceleration on the rocket will be ≈ 11.11 m/s²

Step-by-step explanation:

Here we have

Initial velocity, u = 0 m/s

Final velocity, v = 1000 m/s

Time for increase in velocity. t = 90 seconds

Therefore from the equation of motion, we have

v = u + a × t

From which,

a = (v - u)/t = (1000 - 0)/90 = 100/9 m/s² ≈ 11.11 m/s².

From the above calculation, it is seen that the acceleration of Ms. Weaver and Elon Musk's acceleration on the rocket will be ≈ 11.11 m/s².

Answer:

The answer is 11.1 m/s2

Step-by-step explanation:

Acceleration can be calculated as the change in speed over the total amount of time. In the example given here, it is stated that the top speed of 1000 m/s is reached in a time of 90 seconds.

So if we calculate the acceleration from the information using the formula, we can say that
a = (1000m/s)/(90s) so the acceleration can be found as
a = 11,1 m/s^(2)

I hope this answer helps.
