Problem 5P
Children in a tree house lift a small dog in a basket 4.70 m up to their house. If it takes 201 J of work to do this, what is the combined mass of the dog and basket?
ANSWER:
Step 1 of 2:
Children lift a basket with a small dog to a height specified. The energy needed to lift the dog is given. We are going to find the combined mass of the dog with the basket.
The height through which the dog lifted h = 4.7 m
The energy required E = 201 J
The acceleration due to gravity g = 9.81 m/s2
