To solve this problem it is necessary to apply the concepts related to work and power.
Remember that work is defined as the force applied on a body - or exerted by it - to travel a certain distance, and that the power is that energy mentioned to perform that activity in a given instance of time.
Mathematically work is defined as
Where
d = Distance
At this case the acceleration is the same that gravitational acceleration
At the same time we have that power is defined as
Replacing our values we have that the Work done was
Now substituting this value at the Power equation we have
Therefore the power that she is supplying is 100W.
the weight of the space probe on that planet is 50 N
To calculate the weight of the space probe, we use the formula below.
Formula:
Where:
- W = weight of the space probe on the planet
- m = mass of the space probe
- g = acceleration due to gravity.
From the question,
Given:
Substitute these values into equation 1
Hence, the weight of the space probe on that planet is 50 N
