When plotting a particular kind of energy on a graph, when can we use the equation for the energy(for example, mv² for kinetic energy) to determine the shape of the energy graph?Never, because we have to take into account the other kinds of energy in the system to determine the shapeSometimes, if there are only two kinds of energy in the systemNever, because the shape of an energy graph is not related the equation for that kind of energySometimes, if the horizontal axis on the graph is labeled with the indicator of the energy typeAlways, because the shape of a graph always depends on the equation, even if the variables in the equationdo not appear on the graphAlways, because we are allowed decide where to place y = 0

4) Sometimes in the horizontal Axis on the graph is labelled with the indicator of the energy type

A 1000 kg car traveling at 40 m/s slows to 15 m/s. What is the initial kinetic energy of the car? What is the final kinetic energy of the car? How much work is done on the car in slowing it down? What force does the work on the car? As solved when asked in a different question, I know that the initial kinetic energy is 800,000 J, the final kinetic energy is 112,500 J, and the work is -687500 J. How ever i still need the force.
A cart is loaded with a brick and pulled at constant speed along an inclined plane to the height of a seat-top. If the mass of the loaded cart is 3.0 kg and the height of the seat top is 0.45 meters, what is the potential energy of the loaded cart at the height of the seat top? Referring to the previous item, what will happen to the potential energy of the cart if its mass increases four times?
A kilowatt-hour (kWh) is a unit of measure equal to one thousand watts of electricity being used in one hour. Power companies use this measurement to determine your home energy bill. Consider using a bike for power: It takes 6 minutes pedalling at 24-26 volts consistently to produce just 1/10 (0.1) of a kWh. An average home uses about 25 kWh a day. How long would someone have to pedal at 24-26 Volts to power an average home?
A man is pulling a sled (m-120 Kg) across the snowy tundra (see the figure below) by applying a force of 210 N at an angle of 9-18° with respect to the ground. He pulls the sled over a distance of 100 m. The sled started from rest and reached a final velocity of 6.8 m/s. How much work is done by the man on the sled measured in kJ? (1kJ = 1000J)
The figure below shows an overhead view of two horizontal forces pulling a box along the floor. How much work does each force do as the box is displaced 70 cm along the broken line. What is the total work done by the two forces in pulling the box this distance?
A hiker of mass 73 kg is going to climb to the top of Mount Tam, which has an elevation of 2,574 ft. a) If the hiker starts climbing at an elevation of 545 ft, what will their change in gravitational potential energy be, in joules, once they reach the top? Assume the zero of gravitational potential energy is at sea level. b) Repeat the above calculation for the change in gravitational potential energy, but assume the gravitational potential is zero at the top of the mountain.
Please solve and answer the question correctly. Thank you!
