An object with a mass of 5 kg is dropped and takes 9 s to hit the ground. then another object with a mass of 10 kg is dropped from the same point. how long does it take to hit the ground
It does not matter how heavy the object is, as long as there is no drag or wind interference (such as wind on a feather or piece of paper) the gravitational pull will be equal, therefore the answer is 9s.
