a 90.0-kg man runs at a constant speed of 11.5 m/s. what is his kinetic energy?

Sagot :

Lanuel

The kinetic energy possessed by the man is 517.5 Joules.

Given the following data:

  • Mass = 90.0 kg
  • Velocity = 11.5 m/s.

To find the kinetic energy of the man:

Kinetic energy is an energy that is possessed by a physical object or body due to its motion.

Mathematically, kinetic energy is calculated by using the formula;

[tex]K.E = \frac{1}{2} MV^2[/tex]

Where:

  • K.E is the kinetic energy.
  • M is the mass of an object.
  • V is the velocity of an object.

Substituting the given values, we have;

[tex]K.E = \frac{1}{2}[/tex] × [tex]90[/tex] × [tex]11.5[/tex]

[tex]K.E = 45[/tex] × [tex]11.5[/tex]

Kinetic energy = 517.5 Joules.

Therefore, the kinetic energy possessed by the man is 517.5 Joules.
