A $200$ kg roller coaster is initially moving at $3\mathrm{.}6\frac{m}{s}.$ The ride reaches a maximum height of $22$ m and a top speed of $22\frac{m}{s}.$ Finally, $48$ seconds after starting, the roller coaster comes to rest on a section of track that is $3\mathrm{.}4$ m below the starting height. There are no elastic $($spring$)$ forces involved. For the whole ride, the work done by all non$-$conservative forces combined on the roller coaster is $q,$
