a person of 85 kg is in an elevator.if the elevator is moving at a speed of 5 m/s, what's the person's kinetic energy?keep 4 significant figures


Respuesta :

The kinetic energy of the person would be 1062.5J

Explanation:

Given:

Mass of the person, m = 85kg

Velocity, v = 5m/s

Kinetic energy, KE = ?

We know,

[tex]KE = \frac{1}{2} mv^2[/tex]

Substituting the value in the equation:

[tex]KE = \frac{1}{2} X 85 X (5)^2\\\\KE = 1062.5J[/tex]

Therefore, the kinetic energy of the person would be 1062.5J

Answer:it’s 1,025
