Mass
of a box = 6.0kg
Where = displacement = our required
In this situation work done
Speed

compression
As
Force constant

N/m
Now, work done due to compression is EX 6.49 How many joules of energy does a 100watt light bulb use per hour? How fast would a 70kg 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...
