Question

A 1,500 kg roller coaster is traveling at 32 m/s as it goes over a 6 meter tall hill. What is the kinetic energy of the roller coaster?​

Answer 1

768000 joule

Step-by-step explanation:

As we know that

K.E = 0.5 x mv2

Here m stands for mass, the measure of how much matter is in an object, and v stands for the velocity of the object, or the rate at which the object changes its position.

putting the value we get

K.E = 0.5 x (1500KG)(32 m/s)2

K.E =768000 J
