The answer depends on:
980 meters because 20 seconds = 1960. You divided it by 2.
9.8x10= 98meters
Neither. When a rubber ball gets hot, the rubber begins to lose its elasticity. It doesn't bounce as high. When a rubber ball gets really cold, it starts to behave rather like a rock. It hardly bounces at all The temperature of highest bounce depends on exactly what the ball is made of, but it is probably not all that far from room temperature.

It depends on the rubber band if is a small rubber band then it will go about 20'and if it is an bigger rubber band then it will go about 35' but it depends on the rubber band and the way you shoot the rubber band
This depends on the size of the rubber band, the materials and impurities in the rubber band, and the speed at which you stretch it, as well as the conditions that the rubber band has been under.
Depends on the speed the ball travels.
1,100 to 1,300 feet.
576 feet
If the ball is lighter than the hard ball, then it is because a heavier ball has more force when moving at the same speed as a lighter ball. If they weigh the same, then it is because in some instances, with certain materials, a hard ball with a lot of "ping" to it will bounce further than a rubber ball, due to motive energy being converted to heat in the polymers of the rubber ball, thus decreasing the total motive energy.

Yes it does. If the rubber is to cold the molecules in the rubber will not deflect "spring" allowing. If the rubber is to hot then those same molecules are to far apart to interact with each other in an optimal way.
It has been known since the 16th century that the mass of an object is irrelevant to how far it will fall. The main factor influencing the rate of fall is the shape of the object and, therefore, the air resistance (or buoyancy).
It depends.If the object is a helium balloon, it will not fall on the surface of the earth. If it is a feather, it will fall much more slowly than a ball bearing. A ball bearing will fall much facter on the surface of the earth than it will on the moon.But, if you assume thatthe object is falling under the force of earth's gravity,It is a compact and massive object so that air resistance may be ignored, thens = 0.5*9.8*372 = 6708.1 metres.

It all depends on the weight of the ball but if a tennis ball was thrown it would travel 2 1/2M in 2 seconds but cannot be calculated like this because the further the ball falls the more speed it gains. However there is a trick to this question because the 2nd second is only one second itself. making the answer 1M and 10CM !
the fourth hit will be approx 1.4 metres
