The consumption rate of electricity, in kW/h has increased, on average, at 4.5% per year. If it continues to increase at
this rate indefinitely, find the number of years before the electric companies will need to double their generating
capacity
The electric company will need to double their generating capacity about every years.

Problem 6: During service, a tennis ball is struck at height h = 1.8 m above a tennis court and moves with velocity vo = vo,i.
Assume the ball encounters no air resistance, and use a Cartesian coordinate system with the origin located at the ball's initial
position.
Randomized Variables

We cannot typically “measure” the thickness ofsuch a thin object directly, but the thickness can be determined “indirectly”. Assume that the density of aluminum is2.70 g/cm3 and that the shape of the square aluminum foil is a rectangular cuboid. Then by using the experimental data of the length of the aluminum square 5.10cm, Width is 5.00cm and the mass of aluminum is 0.11g. Determine the thickness of aluminum foil in micrometers.
