Keon Johnson set an NBA combine record with a 1.2192 m vertical jump. If he has a mass of 84 kg, what is his potential energy at the top of his jump? Round your answer to two decimal places.

Keon Johnson has a potential energy of approximately 1004.72 J at the peak of his vertical jump, calculated using the formula for potential energy which takes into account his mass, the height of his jump, and the force of earth's gravity.

Explanation:

The question is asking about the potential energy of NBA player Keon Johnson when he reached the peak of his jump. To find potential energy, we use the equation: Potential Energy (PE) = mass (m) * Gravity (g) * height (h). In this case, the mass (m) is given as 84 kg, the standard value for gravity (g) on Earth is approximately 9.8 m/s² and the vertical jump height (h) is given as 1.2192 m.

So, substituting in the given values:

PE = 84 kg * 9.8 m/s² * 1.2192 m

Therefore, the potential energy of Johnson at the top of his vertical jump is approximately 1004.72 J (Joules) when rounded to two decimal points.
