A man won $5 million by scoring 15 goals in 20 seconds in a contest at a sports game that was sponsored by a business. Did the business risk the $55 million? No! The business purchased event insurance from a company specializing in promotions at sporting events. The event insurance company estimates the probability of a contestant winning the contest and, for a modest charge, insures the event. The promoters pay the insurance premium but take on no added risk as the insurance company will make the large payout in the unlikely event that a contestant wins. To see how it works, suppose that the insurance company estimates that the probability a contestant would win the contest is 0.0002 and that the insurance company charges $2,500. Complete parts (a) Question content area bottom Part 1 a. Calculate the expected value of the profit made by the insurance company.

6. [25] The bent shaft is made to revolve about the vertical axis with a constant angular velocity $\omega$. The slider of weight $W$ is released from rest relative to the rod at $x = 0$. Derive the governing equations of motion and determine the distance $x$ as a function of time $t$ after release. Find also the components of the contact force between the shaft and the slider as a function of time. Neglect friction in your calculations
