1. A ball rolls off a 1.10-meter high table with an initial horizontal velocity of 3.3 m/s. Determine the time required for the ball to fall to the ground and the horizontal distance between the table's edge and the ball's landing location.
2. A cannon ball is shot horizontally off a 25.0-meter high cliff and lands a distance of 141.0 meters from the edge of the
cliff. Determine the initial horizontal velocity of the cannon ball and the time it is in the air
3. A trebuchet launches a stone with an initial velocity of 32 m/s at an angle of 37-degrees from the ground. Determine the
time of flight, the horizontal distance, and the peak height of the stone.

u can solve the problem yourself

-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
