What else can I help you with?
What will be the kinetic energy of an arrow having a potential energy of 50 J after it is shot from a bow?
The kinetic energy of the arrow will also be 50 J, assuming that all the potential energy was converted into kinetic energy when the arrow was shot.
How much energy do you end up with if there is fifty joules of potential energy?
The amount of energy you end up with will still be fifty joules because energy is conserved. If the potential energy is converted to kinetic energy, the total energy remains constant.
What has more potential energy a 50 kilogram stone or a 70 kilogram stone?
The potential energy of an object depends on its height above the ground and its mass. In this case, the 70 kg stone would have more potential energy than the 50 kg stone because it has a greater mass.
If gravity is the only force present what is the total mechanical energy of a book falling off a shelf at a time when its potential energy is 50 J and its kinetic energy is 60 J?
The total mechanical energy of the book falling off the shelf is the sum of its potential energy and kinetic energy. Therefore, the total mechanical energy is 110 J (50 J potential energy + 60 J kinetic energy).
Compare the potential energy of a 20 kg rock on the edge of 100 m cliff with that of a 20 kg rock perched on the edge of a 50 m cliff.?
The potential energy of the rock on the 100 m cliff is twice that of the rock on the 50 m cliff. This is because potential energy is directly proportional to the height of the object above the reference point. So, the higher the cliff, the greater the potential energy.
Will a toy car go faster if the height of the ramp is raised from 20 cm to 50 cm?
Yes, the toy car will likely go faster if the height of the ramp is raised from 20 cm to 50 cm. This is because the higher the ramp, the more potential energy the car will have at the top of the ramp, which will be converted into kinetic energy as it rolls down. The increase in height will result in a greater velocity for the toy car due to the increased gravitational potential energy.

How can kinetic energy turn into potential energy?
first it goes kinetic energy, potential energy, mechanical energy, to chemical energy. kinetic energy- moves energy to provide it potential energy- stores energy to provide energy mechanical energy- uses energy and provides it chemical energy- energy that uses energy to provide energy but...makes the energy that we can use but is bad to use.(not good to use.)

Will an object have more potential energy atop a 50 foot hill or 100 foot hill?
An object will have more potential energy at the top of a 100 foot hill. Gravitational potential energy is directly proportional to height.
Compare the potential energy of a 20 kg rock on the edge of 100 m cliff with that of a 20 kg rock perched on the edge of a 50 m cliff.?
The potential energy of the rock on the 100 m cliff is twice that of the rock on the 50 m cliff. This is because potential energy is directly proportional to the height of the object above the reference point. So, the higher the cliff, the greater the potential energy.
How much Potential energy does a guitar string have that is 50 cm in length with a tension of 50N and displaced 0.8 m at its midpoint?
It's 128 Joules. PE (Potential Energy) = 2(50 N) divided by .50 meters. Multiply that all by (.8m)2
If the potential energy of a swing is 200 J at its highest point and 50 J at its lowest point what is the kinetic energy of the swing at its lowest point if mechanical energy is conserved?
150J, as the potential energy has been converted to kinetic energy as the swing accelerates downwards (and forwards) from the top of its swing. Therefore the decrease in potential energy corresponds directly to the increase in kinetic energy if we are ignoring things like friction. So KE = 200-50= 150
What is the two forms of energy?
Kinetic energy (energy of motion) and potential energy (stored energy) A ball at the top of a building getting ready to be dropped has potential energy, but a ball falling has kinetic energy If the ball is at the top of the building, it has 100% potential and 0% kinetic and when it is halfway from top to bottom and falling it has 50% of each
What is the potential energy of 100 kilogram rocks that is in the 50 meter cabinet?
The potential energy of the rocks can be calculated using the formula PE = mgh, where m is the mass (100 kg), g is the acceleration due to gravity (9.8 m/s^2), and h is the height (50 m). Therefore, the potential energy of the rocks is PE = 100 kg * 9.8 m/s^2 * 50 m = 49,000 Joules.
