if a motorcycle is moving at a speed of 22m/s and has a mass of 375kg what is the kinetic energy

Respuesta :

Answer:

The kinetic energy is 90750 J.

Explanation:

Given:

Mass of the motorcycle is, [tex]m=375\ kg[/tex]

Velocity of the motorcycle is, [tex]v=22\ m/s[/tex]

Kinetic energy of the motorcycle is given as:

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

Plug in 375 for [tex]m[/tex], 22 for [tex]v[/tex] and solve for kinetic energy,[tex]KE[/tex]. This gives,

[tex]KE=\frac{1}{2}\times 375\times 22^2=\frac{1}{2}\times 375\times 484=90750\ J[/tex]

Therefore, the kinetic energy of the motorcycle is 90750 J.
