We will apply the concepts related to Newton's second law. At the same time we will convert everything to the system of international units.
The values of the velocities are,
We know that the acceleration is equivalent to the change of the speed in a certain time therefore
Now applying the Newton's second law we have,
Therefore the approximate magnitude is 8516.36N
Answer:
Potential energy, P = 500 J
Explanation:
We have,
Weight of the box, W = 50 N
Height of the stairs, h = 10 m
It is required to find the potential energy gained by the box. The potential energy is possessed by an object due to its height. The formula of potential energy is given by :
g is acceleration due to gravity
So, the potential energy of 500 J is gained by the box.
