How do you find Ke from friction?
Kinetic Friction Formula
How do I calculate kinetic energy?
In classical mechanics, kinetic energy (KE) is equal to half of an object’s mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m 10 kg) is moving at a velocity of 5 meters per second (v 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.
How much work is done when you push a crate horizontally with 100 N across a 10 m factor floor?
If you push a crate horizontally with 100N across a 10m floor and the friction between the crate and floor is a steady 70N, how much kinetic energy does the crate gain? 12. u0394KE work done (100 N – 70 N)(10 m) (30 N)(10 m) 300 Nm 300 J.
What is his kinetic energy when his potential energy reduces to 1000 J?
What is his kinetic energy when his kinetic energy when his potential energy reduces to 1000 J? PE + KE Total E; KE 10,000 J – 1000 J 9000 J.
