A baseball traveling at 100 mph has more kinetic energy than a baseball traveling at 50 mph because the kinetic energy = 1/2 x mass x velocity. Since the baseballs should have the same mass, the velocity is what will determine which ball has more kinetic energy. Since the 100 mph baseball has a higher velocity than the 50 mph baseball, it has more kinetic energy.
A child climbing a ladder is transforming kinetic energy into potential energy.
The answer is B thank me later !
Answer:
432 km = 432000 m
Explanation:
Primeiro, vamos converter m/s para km/h:
12 m/s = (12 . 3,6)km/h = 43,2 km/h
Agora é só descobrir a distancia que ele percorre em 10 h:
s=43,2.10 = 432 km
Aí se você quiser colocar na medida do Sistema Internacional:
-- Light travels straight, not around in a circle. But if it did, it would cover
a distance equal to the length of the equator in about <em>0.13 second</em>.
-- At the speed of sound (in air at standard temperature and pressure),
it would take about <em>32.6 hours </em>to cover the same distance.
