Unformatted text preview: se the work–energy theorem to find the maximum compression of the spring. Mass of a box = 6.0kg Where = displacement = our required In this situation work done Speed m/s compression As Force constant N/m N/m Now, work done due to compression is EX 6.49 How many joules of energy does a 100-watt light bulb use per hour? How fast would a 70-kg person have to run to have that amount of kinetic energy? Required energy We know that so Energy(E) = (power(P))(time(t)) Power of the bulb Time Mass of a person is Required velocity EX 6.59...
