you could use theta in terms of n like this
theta=20+5n
where n is a whole number between 0 and 10
use your basic algebra to substitute in variables, ie: the for t in dx=Vix*t put dx=Vix*-2Viy/(-9.8m/s^2)
do the same for Vix and Viy, and then again for theta.

break up your Vi=100m/s at 20 degrees into the x&y components
Vix=Vi*cos(20 degrees)
Viy=Vi*sin(20 degrees)
assuming you are on Earth and ingoring air friction
use
Vf=Vi+(-9.8m/s^2)*t
to get
t=(Vf-Vi)/(-9.8m/s^2)
lettin Vf=0 to find time to max height
double it to get the total...
Second one:
Protons are projected at an angle of 300 with an initial speed, given by V0=8.2*105 m/s, in a region of an electric field E=-390j N/C, is present. The proton is to hit a point 1.27 mm in the pos-x direction from the launch point. Find (a) the two porjections angles (theta) that...
Am I interpreting this question correctly?
So, does that mean:
Vector A=8 at 45 degrees
Vector B=8 at 180 degrees
or
Vector A=8 at 45 degrees
Vector B=8 at 225 degrees
I know how to do the problem, it's just interpreting the book's wording on angles.
Thanks
