Answer:

The kinetic energy of a 90 kg mass that is moving with a velocity of 6 m/s is 1620 J.

Explanation:

Given

  • Mass m = 90 kg
  • Velocity v = 6 m/s

To determine

  • Kinetic Energy E = ?

The kinetic energy (K.E) of a body of mass of a 90 kg mass that is moving with a velocity of 6 m/s can be calculated using the formula

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

where

  • m is the mass (kg)
  • v is the velocity (m/s)
  • K.E is the Kinetic energy (J)

substituting m = 90 and v = 6 in the formula

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

[tex]K.E=\frac{1}{2}\left(90\right)\left(6\right)^2[/tex]

       [tex]=\frac{1}{2}\left(90\right)\cdot \:36[/tex]

       [tex]=1620[/tex] J

Therefore, the kinetic energy of a 90 kg mass that is moving with a velocity of 6 m/s is 1620 J.
