Answer:
972 J
Explanation:
At the bottom, all the gravitational potential energy was converted into kinetic energy. If you calculate the GPE, its value will be the same that the KE at the bottom. The GPE can be calculated this way:
GPE = mass×gravity×heigth
GPE = 2.2×9.8×45.08 ≈ 972
<span>The Solar electricity source of
energy comes from the sun’s rays. It is more often in the form of a panel known
as the solar panel. It has a photovoltaic system that generates and supplies
energy in commercial and residential areas. Even though numerous countries are
using this type of electricity to save electric-induced power, it is not used
for a number of reasons. One is that 1 panel with a size of 6 by 10 solar cells
is expensive. There are countries who cannot afford to buy them. Two, it
requires a larger area to place the panel. Three, the efficiency is low. The smaller
the panel is, the lower its efficiency and therefore produces lesser power to
generate a specific area. </span>
Answer: Car brakes produces more energy then the bicycle because the cars wheels produces a much bigger force that makes the car go and to stop that force the car uses greater amount of energy that transfers to heat but in a bicycle the wheels do not turn that fast so when you press the break there is less energy that transfer to heat.
