Question
What is the value of the kinetic energy when the velocity of the object is
54 Km/h
- 500J
- 2000J
- 4500J
- 8000J
Hint:
When the velocity increase to 54Km/h, the kinetic energy increase to 4500 J.
The correct answer is: 4500J
- The graph shows a gradual increase in the kinetic energy as the velocity increase.
- By intersection the graph at the points where velocity and the kinetic energy meets, the value of kinetic energy can be derived.
- If the velocity is 54 Km/h, the kinetic energy would be 4500 J.
