29. A boy lifts a book with the weight of 30.0 N from the floor to the top of a table, a vertical distance of 2.0. meters. Compute the increase in the potential energy of the weight.
Remember to include your data, equation, and work when solving this problem.

Respuesta :

Answer:

60J

Explanation:

Since the book's weight is 30N and weight = mass * gravity (around 10m/s²):

30 = X * 10 ===>   X = 3.

Using the potential energy formula we have Gravity * Height * Mass:

10 * 2 * 3 = 60J
