you can find it using the equation: potential energy=mass*gravitational acceleration*height.
energy=50kg*9.8N/kg*40m=19600Nm=19600J or 19.6kJ
Sometimes they use 10 instead of 9.8 for the g constant.

Answer:
If the force on a cart doubles, the acceleration of the cart doubles.
Explanation:
For this problem, we need to consider the following equation:
Force = Mass x Acceleration
We can reasonably assume that the cart will have constant mass in the given force system. With this assumption we can say the following relationship:
Force is directly proportional to Acceleration within the system.
Given that our force on the cart is doubled, then our acceleration of the cart must also be doubled. You can mathematically express this as follows:
F = MA
2F = M * 2A
Hence, if force doubles, the acceleration doubles.

Explanation:
Because it is one of the demerit of a machine
The answer to your question Tropical Cyclones
The statement that describes the error in the work is that the distance must be converted to meters (m).
<h3>FORMULA FOR WORK:</h3>
Work can be calculated by using the following formula:
W = F × d
Where;
- W = work done
- F = force (N)
- d = distance (m)
According to this question, the force is given as 140N and the distance is given as 30cm. The force is calculated as follows:
F = 140N × 30cm = 4200J
This calculation is erroneous because the unit of distance should be converted from cm to meters.
