Consider a 10 kg projectile launched with an initial speed of 100 m/s at an angle of 35 degrees elevation. The Resistance force is R=-bv where b=10 kg/s. A) Use a numerical method to determine the horizontal and vertical positions of the projectile as a function of time. B) What is the range of the projectile? C) Determine the elevation angle that gives the maximum anle. (Hint: Adjust the elevation angle by the trial and error to find the greatest range).

2. Relevant equations

ƩF=ma

3. The attempt at a solution

I am trying to come up with an equasion for part a, but I am getting confused. Could anyone help?

I tried:

I made a free body diagram with up being positive y direction and right being positive x direction.

I set ƩFx= -(Vx)bv=mAx

ƩFy= - mg - (Vy)bv=mAy

I am not sure if this is right or where to go from here. Can someone help please and thank you.
