Final answer:
The amount of energy transferred while lifting weights is 784 Joules.
Step-by-step explanation:
In order to determine the amount of energy transferred while lifting weights, we can use the formula:
Energy = mass × gravitational acceleration × height
In this case, the mass of the weights is 40 kg and the height is 2 m. The gravitational acceleration can be taken as 9.8 m/s². Plugging in these values, we get:
Energy = 40 kg × 9.8 m/s² × 2 m = 784 Joules
Therefore, the amount of energy transferred while lifting the weights is 784 Joules.
