Question

75 kg man walking at 1.0 m/s. calculate the kinetic energy

Answer 1

To calculate the kinetic energy of the man, we use the formula:

Kinetic Energy = 1/2 * mass * velocity^2

Given:
Mass = 75 kg
Velocity = 1.0 m/s

Plugging in the values:

Kinetic Energy = 1/2 * 75 kg * (1.0 m/s)^2
Kinetic Energy = 1/2 * 75 kg * 1 m^2/s^2
Kinetic Energy = 1/2 * 75 kg * 1
Kinetic Energy = 1/2 * 75 kg
Kinetic Energy = 37.5 kg*m^2/s^2

Therefore, the kinetic energy of the man walking at 1.0 m/s is 37.5 joules.
