Web7.11. The quantity 1 2 mv 2 in the work-energy theorem is defined to be the translational kinetic energy (KE) of a mass m moving at a speed v. ( Translational kinetic energy is distinct from rotational kinetic energy, which is considered later.) In equation form, the … WebThe right hand side = kinetic energy and the left is the same. You are given mass and velocity. Their product gives you momentum (p). If you square the momentum and divide the result by double the mass, you get Kinetic energy in Joules if mass is in kg, velocity in metres/second. 1 Jackery Power Works at Jackery (2012–present) Updated 6 h Promoted
WebTo calculate the kinetic energy, first convert km/h to meters per second: 40km/h = 11.11 m/s. Using the first kinetic energy equation above, replace the values for m and v and get KE = 2200 · (11.11) 2 / 2 = 135775.3 Joules or 135.7753 kiloJoules.
