Answer:
1. 2.98m/s
2. 0.28m
Explanation:
The energy equation would work great in this scenario:
E=K+U. Since all of our energy comes from gravitational potential energy, and we are interested in finding the kinetic energy, all our mechanical energy must be in kinetic form, therefore:

We can use energy to find max height.
For energy, set the equation E=K+U as 437.7=(mass adult+mass senior)gh:

Answer:
The answer is: dense air exerts more pressure than less dense air.
Pressure is due to the weight of the above column of the substance which is a force resulting from its weight that is the product of its mass and gravitational pull. The denser the air and the grater the column, the larger its mass and hence the more the pressure it exerts.
