## Question:

A metal ball with mass m = 0.15 kg is dropped from rest in a fluid. The magnitude of the resistance due to the fluid is given by ${ C }_{ d }\upsilon$ , where ${ C }_{ d }$ is a drag coefficient and $\upsilon$ is the ball’s speed. If ${ C }_{ d }$ = 2.1 kg/s, determine the total work done on the ball from the moment of release until the ball achieves 99% of terminal velocity.
