Question

In Question 2 (the question before the last one), if the mass of the pop-up toy is 0.008 kg, what will be the pop-up toy's gravitational potential energy at the peak of its rise?

1) 0.085 J
2) 0.054 J
3) 0.068 J
4) 0.15 J

Answer 1

The gravitational potential energy of the pop-up toy at its peak can be calculated using the formula E = mgh, where m is mass, g is the acceleration due to gravity, and h is the height. However, the height is necessary to complete this calculation and it has not been provided.

Step-by-step explanation:

To calculate the pop-up toy's gravitational potential energy at the peak of its rise, we can use the formula for gravitational potential energy, which is E = mgh, where:

• m is the mass of the object,
• g is the acceleration due to gravity (9.8 m/s2 on Earth), and
• h is the height above the zero level (which could be the height reached at the peak).

We are not provided with the height (h) in this question, so we are unable to calculate the energy without it. However, assuming we had the height and based on the fact that the mass of the toy is 0.008 kg, we would plug in the values into the equation to find the gravitational potential energy in joules. For instance, if the toy reached a peak height of h meters, the calculation would look like this: E = 0.008 kg * 9.8 m/s2 * h m.

Since we can't complete the calculation without the missing value, we would need the height to answer the student's question accurately.
