Question: 1 the velocity v of a falling parachutist is given...

Question details

1. The velocity v of a falling parachutist is given by y-e Where g 9.8 m/s. For a parachutist with a drag coefficient c 14 kg/s, compute the mass m so that velocity is v 35 m/s att-7s First use Incremental Search Method and then use Bisection Method. The Incremental Search method will also provide you the initial interval in which the root lies. 2. Water is flowing in a trapezoidal channel at a rate of Q-20 cubic meter per second. The critical depth y for such a channel must satisfy the equation: 0-1where g-9.81m/s, A, the cross-sectional area(m2) and B is width of the channel at the surface (m). For this case, the width and the cross-sectional area can be related to depth y by: B-3+y and.4,-3y+Solve for the critical depth using (a) the graphical method and (b) Bi-section method; use part (a) for the initial interval.
