Using the given formula with v0=56 ft/s and h=40 ft
h = -16t2 + v0t
40 = -16t2 + 56t
16t2 - 56t + 40 = 0
Solving the quadratic equation:
t= (-b+/-(b^2-4ac)^1/2)/2a = (56+/-((-56)^2-4*16*40)^1/2)/2*16 = (56 +/- 24) / 32
We have two possible solutions
t1 = (56+24)/32 = 2.5
t2 = (56-24)/32 = 1
So initially the ball reach a height of 40 ft in 1 second.
Answer: DENVER, COLORADO
Explanation: Temperature inversion is the term used to describe the increase in temperature as the height increases towards the Toposphere, Temperature inversion is a reverse of the normal temperature flow or distribution in the atmosphere.
Denver, Colorado has been known to be one of the Cities of the World where temperature inversion occurs frequently. The TOPOGRAPHY of Denver, Colorado makes it prone to temperature inversion, Denver, Colorado is located at the foot of mountains.
Efficiency. The ratio of energy which was transferred to a useful form compared to the total energy initially supplied is called the efficiency of the device. Efficiencies can be written as decimals like 0.33 or percentages 33%. To convert a efficiency expressed as a decimal to a percentage you need to multiply by 100.
