determine the kinetic energy of a boy mass 40kg running with velocity of 3m/s
KE = 0.5M*V^2.
determine the kinetic energy of a 40 kg woman running with a velocity of 4 m/s?
To determine the kinetic energy of a boy, we can use the equation:
Kinetic Energy (KE) = 0.5 * mass * velocity^2
Given:
Mass (m) = 40 kg
Velocity (v) = 3 m/s
Substituting the values into the equation, we get:
KE = 0.5 * 40 kg * (3 m/s)^2
= 0.5 * 40 kg * (9 m^2/s^2)
= 0.5 * 360 kg * m^2/s^2
= 180 kg * m^2/s^2
Therefore, the kinetic energy of the boy is 180 kilogram-meter squared per second squared (kg·m²/s²).
To determine the kinetic energy of the boy, we will use the formula:
Kinetic Energy (KE) = 0.5 * mass * velocity^2
Given:
Mass (m) = 40 kg
Velocity (v) = 3 m/s
Substituting the values into the formula, we get:
KE = 0.5 * 40 kg * (3 m/s)^2
= 0.5 * 40 kg * 9 m^2/s^2
= 0.5 * 360 kg m^2/s^2
= 180 kg m^2/s^2
Therefore, the kinetic energy of the boy is 180 kilogram meters squared per second squared (kg m^2/s^2).
