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?

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

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.

total distance travelled = 60 miles

total time taken =1.5 hours

average speed = total distance / total time

60 / 1.5

= 40

therefore, average speed = 40 m/h
