Use principles of physics to solve the problem and then verify
your answer using the simulation. Assume that the acceleration due
to gravity has a magnitude of g = 9.80 m/s2. If the range of the
projectile is 5.96 m, the time-of-flight is T = 1.20 s, and air
resistance is turned off, determine the following. A. What is the
launch angle of the projectile? B. What is the initial speed of the
projectile? C. Express the maximum height reached...
a) verify that y1 and y2 are fundamental solutions
b) find the general solution for the given differential
equation
c) find a particular solution that satisfies the specified
initial conditions for the given differential equation
1. y'' + y' = 0; y1 = 1 y2 = e^-x; y(0) = -2 y'(0) = 8
2. x^2y'' - xy' + y = 0; y1 = x y2 = xlnx; y(1) = 7 y'(1) =
2
y''+ 3y'+2y=e^t
y(0)=1
y'(0)=-6
Solve using Laplace transforms.
Then, solve using undetermined coefficients.
Then, solve using variation of parameters.
