KE= 0.5mv2
so we have KE=50
m=50
v=1.414m/s
The gain in kinetic energy can be calculated using the equation: ΔKE = KE_final - KE_initial, where KE is the kinetic energy. Simply subtract the initial kinetic energy from the final kinetic energy to determine the gain.
There is no single answer. Velocity is relative, and that means that the kinetic energy of a body also is relative. To calculate the kinetic energy you have to choose a reference frame, and the answer will be different depending on if you choose the person, the belt of the treadmill or the moon. Neither answer is more right or wrong than any other.
Kinetic energy is possessed by moving bodies so that is easy. Potential energy comes in different forms - gravitational for instance due to height above the surface of the earth. Other forms like chemical, nuclear, elastic, are not so obvious, you need to know the properties of the material before it can be estimated.
Heat is just the measure of the average kinetic energy of the molecules in... whatever you are measuring. Kinetic energy is s form of energy, so the fact that the molecules have kinetic energy proves heat is energy. Also heat powered engines do work by converting heat into kinetic energy. ============================ Thanks for that. But how do you prove that heat is a form of energy ? ============================
The kinetic energy of the truck can be calculated using the formula KE = 0.5 * m * v^2, where m is the mass of the truck and v is its velocity. First, convert 22500 lb to kg (1 lb ≈ 0.4536 kg) and 55 mph to m/s (1 mph ≈ 0.44704 m/s). Then plug the values into the formula to calculate the kinetic energy in joules.

Kinetic energy is equal to one-half of the product of an object's mass and the square of its velocity. Velocity is change in displacement divided by time. If you have the kinetic energy and mass, you can calculate the velocity by taking the square root of the quotient of kinetic energy and mass, and thereby solving for the velocity.
The kinetic energy of the boulder can be calculated using the formula KE = 0.5 * m * v^2, where m is the mass of the boulder and v is its velocity. If we know the velocity of the boulder when it has fallen 500m, we can calculate its kinetic energy using this formula.
To determine the velocity of an object using its potential energy, you can use the principle of conservation of energy. By equating the potential energy of the object to its kinetic energy, you can calculate the velocity of the object. The formula to use is: Potential Energy Kinetic Energy 1/2 mass velocity2. By rearranging this formula, you can solve for the velocity of the object.
You can calculate kinetic energy using the formula KE = 0.5 * m * v^2, where m is the mass of the object and v is its velocity. If the final velocity is not given, you would need more information or assumptions to solve for kinetic energy.
The kinetic energy of an object is calculated using the equation KE = 0.5 * m * v^2, where m is the mass of the object and v is its velocity. To determine which object has more kinetic energy, compare the values of mass and velocity for each object. The object with the higher mass or velocity will have more kinetic energy.
Velocity can be determined using kinetic energy by using the formula: kinetic energy 0.5 mass velocity2. By rearranging the formula, one can solve for velocity by dividing the kinetic energy by 0.5 times the mass, and then taking the square root of the result.
The kinetic energy of a jeepney depends on its mass and velocity. The kinetic energy equation is KE = 0.5 * mass * velocity^2. Given the mass and velocity of the jeepney, the kinetic energy can be calculated using this formula.
The formula of kinetic energy (for nonrelativistic speeds) is: KE = (1/2)mv2 That is, 1/2 times the mass times the speed squared.
You can calculate the kinetic energy just before hitting the ground using the formula for potential energy and kinetic energy. First, calculate the potential energy at the initial height using mgh (mass x gravity x height). Then equate this value to the kinetic energy just before hitting the ground using the formula 1/2mv^2 (0.5 x mass x velocity squared) and solve for the velocity.
To calculate displacement using the work-energy equation, first calculate the work done on the object using the force applied and the distance moved. Then, equate the work done to the change in kinetic energy of the object using the work-energy equation: Work = Change in kinetic energy = 0.5 * mass * (final velocity^2 - initial velocity^2). Finally, rearrange the equation to solve for displacement.
You can determine the kinetic energy of a sky diver above Earth by using the formula: KE = 0.5 * m * v^2, where KE is kinetic energy, m is mass, and v is velocity. You can calculate the velocity of the sky diver using the equation of motion and then plug it into the formula to find the kinetic energy.
