Question
Pleas solve this
Two carts are initially at rest on a table top. One has a mass of 0.5 kg and the other has a mass of 0.25 kg. You push each of them with a force of 1 N over a distance of 1 m. Which cart will have the greater kinetic energy? Ignore friction. The lighter cart has more kinetic energy because it will be moving at a greater speed by the end of the 1 m. We need more information. They both have the same kinetic energy. The heavier cart has more kinetic energy because kinetic energy is proportional to mass.Explanation / Answer
work done on cart with mass (0.25 KG) = 1*1 = 1 Joule
KE = work = 1J (principle of energy conservation)-------------(1)
work done on cart with mass (0.5 KG) = 1*1 = 1 Joule
KE = work = 1 J (principle of energy conservation)--------------(2)
from (1) and (2) we can say that both have same kintic energy
so, OPTION C IS CORRECT
