Orbit circumference
<span>= 2 pi *1.9*10^7 miles </span>
<span>time for orbit trip = 2.9*10^7 s </span>
<span>speed = 2 pi *1.9 / 2.9 miles/second </span>
<span>= 4.12 miles/second </span>
<span>You did not say what units </span>
<span>in miles per hour, multiply by 3600 and get </span>
<span>14,820 miles/hour</span>
Explanation:
Given that,
Net force = 135.5 N
Mass = 26.7 kg
(a). We need to draw a free body diagram
A force is exerted on a object.
(b). We need to calculate the acceleration
Using formula of acceleration



(c). We need to draw the sketch a position vs. time graph for the object.
Using equation of motion

Put the value into the formula


(d). We need to draw the sketch a velocity vs. time graph for the object.
Using equation of motion

Put the value into the formula


(e). We need to calculate the distance travel in 8.82 s
Using equation of motion



Hence, This is the required solution.
The answer is C. I hope this helps you.
Balance and beaker of water. The balance will measure mass and the beaker will measure the volume when you take the initial volume without the key subtracting that value from the value with the key in the beaker
