An 82 kg jogger has 810 J of kinetic energy. What is the jogger’s velocity?
Calculating Jogger's Velocity with Kinetic Energy
Kinetic Energy (KE) = 0.5 * mass * velocity^2
Given that the kinetic energy (KE) of the jogger is 810 J and the mass is 82 kg, we can rearrange the formula to solve for velocity:
810 J = 0.5 * 82 kg * velocity^2
First, divide both sides by 0.5 * 82 kg:
velocity^2 = 810 J / (0.5 * 82 kg)
Calculate the value:
velocity^2 = 9.878
Finally, take the square root of 9.878 to find the jogger's velocity:
Velocity = √9.878 ≈ 4.4 m/s
Therefore, the jogger's velocity is approximately 4.4 m/s.
An 82 kg jogger has 810 J of kinetic energy. What is the jogger’s velocity?
Answer: 4.4 m/s Explanation: The jogger's velocity is approximately 4.4 m/s based on the given kinetic energy and mass.
