4. A small dog is trained to jump straight up a distance of 1.2 m. How much kinetic energy does the 7.2-kg dog need to jump this high? (The acceleration due to gravity is 9.8 m/s².) 85 J 18.2 J 9.8 m/s There is not enough information.
The energy required to move some distance while experiencing a force is equal to the force times the distance. Force is equal to mass time acceleration.
85 j is the answer the formula is 7.2 * 9.8 * 1.2 = 84.67200
sorry to reawaken a dead thread, but I gotta thank @fosterthepeople for actually explaining this, it helped with a similiar problem, except the values were changed.
