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 can use the following equation:
Kinetic Energy = 0.5 * mass * velocity^2
First, let's calculate the kinetic energy using the given values:
Mass (m) = 72.6 kg
Velocity (v) = 7.3 m/s
Plugging these values into the equation:
Kinetic Energy = 0.5 * 72.6 kg * (7.3 m/s)^2
Now, we can simplify and solve the equation:
Kinetic Energy = 0.5 * 72.6 kg * 53.29 m^2/s^2
Kinetic Energy = 1952.097 J
Therefore, Ralph's maximum kinetic energy is approximately 1952.1 Joules.
