Suppose that a parachutist with linear drag (m=50 kg, c=12.5kg/s) jumps from an airplane flying at an altitude of a kilometer with a horizontal velocity of 220 m/s relative to the ground.
a) Write a system of four differential equations for x,y,vx=dx/dt and vy=dy/dt.
b) If theinitial horizontal position is defined as x=0, use Euler’s methods with t=0.4 s to compute the jumper’s position over the first 40 s.
c) Develop plots of y versus t and y versus x. Use the plot to graphically estimate when and where the jumper would hit the ground if the chute failed to open.
A 200 gallon tank initially contains 100 gallons of water with 20 pounds of salt. A salt solution with 1/5
pound of salt per gallon is added to the tank at 10 gal/min, and the resulting mixture is drained out at 5
gal/min. Let Q(t) denote the quantity (lbs) of salt at time t (min).
(a) Write a differential equation for Q(t) which is valid up until the point at which the tank overflows.
Q' (t) =
=
(b) Find the quantity of salt in the tank as it's about to overflow.

The flight of a model rocket can be modeled as follows. During the first 0.15 s the rocket is propelled upward by the rocket engine with a force of 16 N. The rocket then flies up while slowing down under the force of gravity. After it reaches the apex, the rocket starts to fall back down. When its downward velocity reaches 20 m/s, a parachute opens (assumed to open instantly), and the rocket continues to drop at a constant speed of 20 m/s until it hits the ground. Write a program that calculates and plots the speed and altitude of the rocket as a function of time during the flight.arrow_forwardAn aluminum wire having a cross-sectional area equal to 4.60 x 10-6 m? carries a current of 7.50 A.
