I need help with a problem involving a switch statement. I need to use switch to write a program that can compute the maximum height of the projectile, the total horizontal distance traveled, or the time to hit. It also asks that it should accept as input v0, A, and g.
I am suppose to test the program with:
v0=40, A=30, g=9.81
I am given height
h(t)=v0*t*sin(A)-0.5g*t^2 (g=gravity)
velocity:
v(t)=sqrt(v0^2-2*v)*t*sin(A)+g^2*t^2

So then you need user input to indicate which operation to perform, and then you just need to switch on the user input and perform the requested operation. The documentation of switch should make it clear how to use switch in such a basic mode.
