Question


What is the value of the kinetic energy when the velocity of the object is
18 Km/h

  1. 500J
  2. 2000J
  3. 4500J
  4. 8000J

hintHint:

According to the graph given, the velocity is directly proportional to the kinetic energy. If the velocity is 1800 Km/h, the kinetic energy is 500 J.

The correct answer is: 500J


    • The kinetic energy changes according to the increase or decrease in velocity.
    • The graph show the increase in the kinetic energy according to the increase in velocity.
    • The kinetic energy is 500 J when the velocity is 1800 Km/h.
