A44.2 kg diver steps off a diving board and drops straight down into the water. the water provides an average net force of resistance of 1535 n to the diver’s fall. if the diver comes to rest 5.7 m below the water’s surface, what is the total distance between the diving board and the diver’s stopping point underwater? the acceleration due to gravity is 9.81 m/s 2 . answer in units of m.

The total distance between the diving board and the diver’s stopping point underwater is 20.18 m.

Explanation:

Given that,

Average net force = 1535 N

Distance = 5.7 m

Mass of diver = 44.2 kg

We need to calculate the total distance between the diving board and the diver’s stopping point underwater

Using relation of energy and work done

The energy the diver had when hitting the water has to equal the upward force and distance in the water.

Hence, The total distance between the diving board and the diver’s stopping point underwater is 20.18 m.

-first use of geothermal energy occurred more than 10,000 years ago in north america by american paleo-indians

-the first industrial use of geothermal energy began near pisa, italy in late 18th century

-in 1904, italian scientist piero ginori conti invented the first geothermal electric power plant in which steam was used to generate the power

-with the above experiment, the first geothermal plant in usa started in 1922 with a capacity of 250 kilowatts

-however, in 1946 first ground-source geothermal heat pump installed at commonwealth building in portland, oregon

-during the 1960’s, pacific gas and electric began operation of first large scale geothermal power plant in san francisco, producing 11 megawatts

-in 1973, when oil crisis began many countries began looking for renewable energy sources and by 1980’s geothermal heat pumps (ghp) started gaining popularity in order to reduce heating and cooling costs

-as effect of climate change started showing results, governments of various countries joined hands to fight against it, for which kyoto protocol was signed in japan in 1997, laid out emission targets for rich countries and required that they transfer funds and technology to developing countries, 184 countries have ratified it

hope this

force tends to be low and long diustance masses are high
