How much kinetic energy is lost in joules
WebA two-ton car (2,000 kg/4,409 lb) traveling 50 miles per hour (mph) has a total kinetic energy value of 499,612 Joules. That same car at 10 mph has 19,984 Joules of kinetic energy. A one-pound (454g) toy car traveling at 10 mph has 4.5 Joules of kinetic energy. Let’s … 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. Example 2: A ball which …

WebSo first we know that all the potential energy was converted into kinetic energy. We had 100 joules of potential energy, so we're still going to have 100 joules, but now all of it's going to be kinetic energy. And kinetic energy is 1/2 mv squared. So we know that 1/2 mv squared, or the kinetic energy, is now going to equal 100 joules. What's ... WebFor example, in Denmark rifle ammunition used for hunting the largest types of game there such as red deer must have a kinetic energy E 100 (i.e.: at 100 m range) of at least 2700 J and a bullet mass of at least 9 g or alternatively an E 100 of at least 2000 J and a bullet …
