how much kinetic energy does a roller coaster have if its mass is 3000 kg and is moving at 30 m/s

Respuesta :

TaylorBayley
The Kinetic energy of an object is given by:
[tex]E_k= \frac{1}{2}mv^2 [/tex]

Where m is the mass of the object (kg) and v is the velocity of the object (ms-1)

Substituting in:
[tex]E_k= \frac{1}{2}*3000*30^2 = 1350000J[/tex]
Therefore the Kinetic energy of the object is 1.35MJ
