Power = (work done) / (time to do the work)
Work done = (force to lift the object) x (distance lifted)
In this question, the force is the (weight of the basket)+(your weight).
Work done = (weight of basket+you) x (3 meters)
Time to do the work = 6 seconds.
Power = (weights x 3 meters) / (6 seconds)
<em>Power = (1/2)·(weight of the basket+you, in Newtons) watts</em>
Answer:
Explanation:
I cant really see the equation
Answer:
E - Lift-off for the return trip from Phobos requires much less fuel than that from Mars because of Phobos weaker gravitational pull.
Explanation:
Fuel requirement might be lesser in case of Phobos expedition.
This explains the fact that fuel consumption during lift off from Phobos is greater than the fuel consumption during lift off from Mars. Therefore E is the best answer.
