Suppose a car has 4000 J of kinetic energy. What will be its kinetic energy if the speed is doubled? What if the speed is tripled? |
|
Answer» Solution :When speed is doubled , KE will increase FOUR TIMES. Hence, KE=4000 x 4 =16000 J or 16 kJ When the speed is tripled, KE will become nine times. Hence, KE=4000 x 9 = 36000 J or 36 kJ |
