Answer:

KE = 8.4 kJ

Step-by-step explanation:

given,

mass of the roller-coaster = 364 Kg

speed of the roller-coaster car = 6.8 m/s

kinetic energy = ?

Kinetic energy is the energy related to the motion of the body.


KE = (1)/(2)mv^2


KE = (1)/(2)* 364 * 6.8^2

KE = 8415.68 J

KE = 8.4 kJ

Hence, the kinetic energy of the roller coaster of the moving car is equal to KE = 8.4 kJ
