Determine the drag coefficient c needed for a parachutist of mass m = 68.1 kg to have a velocity of v = 40 m/s after free-falling for time t = 10 s. let the acceleration of gravity be g = 9.8 m/s2. recall the equation for free-fall velocity of an object:
(a) using calculus knowledge, follow example 1.1 to obtain the analytical solution for the velocity the case where the jumper is initially at rest (v = 0 at t = 0).
(b) repeat the numerical calculation for the velocity with the same initial condition and parameter values. use a value of 0.225 kg/m for.
(c) program in excel to obtain the analytical solution and numerical solution from t=0 to 20 seconds. plot both solutions in the same figure. provide me your programming code and figure.

First, launch the video below. you will be asked to use your knowledge of physics to predict the outcome of an experiment. then, close the video window and answer the question at right. you can watch the video again at any point. part a as in the video, we apply a charge +q to the half-shell that carries the electroscope. this time, we also apply a charge –q to the other half-shell. when we bring the two halves together, we observe that the electroscope discharges, just as in the video. what does the electroscope needle do when you separate the two half-shells again? view available hint(s) as in the video, we apply a charge + to the half-shell that carries the electroscope. this time, we also apply a charge – to the other half-shell. when we bring the two halves together, we observe that the electroscope discharges, just as in the video. what does the electroscope needle do when you separate the two half-shells again? it deflects more than it did at the end of the video. it deflects the same amount as at end of the video. it does not deflect at all. it deflects less than it did at the end of the video. submit

When a bicycle coasts uphill, it moves slower and slower as it climbs. why? a. its kinetic energy is transforming into heat energy. b. its potential energy is transforming into kinetic energy. c. its kinetic energy is transforming into potential energy and heat energy. d. its potential energy is transforming into kinetic energy and heat energy.
