Ralph is also swinging at the park. He has a mass of 72.6 kg, and his maximum velocity at the lowest point in his swing is 7.3 m/s. What is Ralph’s maximum kinetic energy?
To calculate Ralph's maximum kinetic energy, we need to use the formula:
Kinetic energy = (1/2) * mass * velocity^2
Step 1: Gather the given information
- Ralph's mass: 72.6 kg
- Ralph's maximum velocity: 7.3 m/s
Step 2: Plug the values into the formula
Kinetic energy = (1/2) * 72.6 kg * (7.3 m/s)^2
Step 3: Calculate the result
Kinetic energy = (1/2) * 72.6 kg * 53.29 m^2/s^2
Step 4: Simplify the expression
Kinetic energy = 1935.261 J (rounded to three decimal places)
Therefore, Ralph's maximum kinetic energy is approximately 1935.261 Joules.
