In this problem, we consider an equation in differential form: M dx + N dy = 0. Given equation: 5x + 7y dx - 7x + 2y dy = 0. Find: M_u N_r. If the problem is exact, find a function F(x, y) whose differential, dF(x, y), is the left-hand side of the differential equation. That is, level curves F(x, y) = C give implicit general solutions to the differential equation. If the equation is not exact, enter NE. Otherwise, find F. Note: You are not asked to enter C. F(x, y)

The proposed design for an energy-absorbing bumper for a car exerts a decelerating force of magnitude $bs + cv$ on the car when it collides with a rigid obstacle, where $s$ is the distance the car travels from the point where it contacts the obstacle and $v$ is the car's velocity. Thus the force exerted on the car by the bumper is a function of the car's position and velocity. (a) Suppose that at $t = 0$ the car contacts the obstacle with initial velocity $v_0$. Prove that the car's position is given as a function of time by $s = \frac{v_0}{2h} \left[ e^{-(d-h)t} - e^{-(d+h)t} \right]$, where $d = c/2m$, $h = \sqrt{d^2 - b/m}$, and $m$ is the mass of the car. To do this, first show that this equation satisfies Newton's second law. Then confirm that it satisfies the initial conditions $s = 0$ and $v = v_0$ at $t = 0$. (b) Investigate the effects of the car's mass, the initial velocity, and the constants $b$ and $c$ on the motion of the car when it strikes the obstacle. (Assume that $d^2 > b/m$.) Pay particular attention to how your choices for the constants $b$ and $c$ affect the maximum deceleration to which the occupants of the car would be subjected. Write a brief report presenting the results of your analysis and giving your conclusions concerning the design of energy-absorbing bumpers. (c) Repeat part (a) if the surface is inclined with the given angle theta. Choose some typical numbers for the variables used above and plot the car's position as a function of time.
