A high jumper reaches a height of 2.1 m. If they have a mass of 65 kg, what is the gravitational potential energy at the highest point in the jump?

Answer:

[tex]\boxed {\boxed {\sf 1337.7 \ Joules}}[/tex]

Explanation:

We are asked to find the gravitational potential energy at the highest point in the jump.

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field. It is calculated using the following formula:

[tex]GPE= m \times g \times h[/tex]

The mass of the jumper is 65 kilograms and they reach a height of 2.1 meters. Assuming this situation is occurring on Earth, the acceleration due to gravity is  9.8 meters per second squared.

  • m= 65 kg
  • g= 9.8 m/s²
  • h= 2.1 m

Substitute the values into the formula.

[tex]GPE = 65 \ kg \times 9.8 \ m/s^2 \times 2.1 \ m[/tex]

Multiply the numbers together.

[tex]GPE=637 kg*m^2/s^2 \times 2.1 \ m[/tex]

[tex]GPE=1337.7 \ kg*m^2/s^2[/tex]

Convert the units. 1 kilogram meter squared per second squared is equal to 1 Joule, so our answer of 1337.7 kg*m²/s² is equal to 1337.7 J.

[tex]GPE= 1337.7 \ J[/tex]

The gravitational potential energy at the highest point in the jump is 1337.7 Joules.
