Hardness Energy
Pls me ... Psychic xplain this homework?
Need help with your homework on a psychic? Order on the surface of the metal mass 4.0kg is dropped 0.8m horizontal distance it Hardness test. 1) 0.8m through the bulk, how much potential gravitional Is the transformation of energy has been lost? 2) How much kinetic energy of the Mass is held horizontally just hit the surface? 3) body Speed just before hitting the surface is horizontal? 4) 90% of the energy that is supposed to heat energy, how much heat energy When the body is horizontal to the surface to produce hits?
1. Caused by the gravitational acceleration g multiplied by the volume of potential, I Energy and the H H P = mgh: P a = 4.0 * 9.81 * 0.8 = 31.4 J 2. Exactly First, such as the potential energy: 31.4J. The height of the metal surface All of the above potential energy is converted into kinetic energy is 0. 3. She walks through the speed v, the kinetic energy (1 / 2) mV ^ 2. This equates The original potential energy: (1 / 2) mV ^ 2 = mgh v a ^ 2 = 2gh v a = sqrt (2 * 9.81 * 0.8) v the = 3.96 l / s, 4. 31.4 Japanese answer to the 2-90% multiplied by 28.3 = J
