Question

At what height must a 50 kg bag be raised for its potential energy to be 34.354 J?

Answer 1

Answer:

To calculate potential energy we use the formula mgh where m is mass g is acceleration due to gravity and h is the height of the object.

Explanation:

Given

Potential energy is 35.354j

Weight(it is the force due to gravity)=50 N

We know that force =m X g

So we got energy and the value of mg

So height=50/34.354

H=1.45543459 or 1.5 (approximately)
