lol just used Firefox as my browser and willem2s formula looks far more comprehendable Yes willem2 I did reach that formula after some revisions. I didn't square the Velocity of the projectile (bullet). Although after solving the same equation for theta are you able to reach my formula of...

Sooo the formula for the angle needed is? I don't mean for this to sound rude. I solved another problem in my textbook very similar to this one where a fire hose shot water at a velocity of 6.5 m/s. I had to determine was angle(s) the nozzle could be at to reach a target 2.5 meters away. I...

How might you have it willem2?

Yes, I did this to solve for T. Afterwords I multiplied that formula by 2 in order to determine the total air time. Once I found the total air time formula T= 2Fsin(θ)/2 I plugged it into the formula X = X° + Vxo * T. Was this an incorrect strategy?

I just got curious today and tried to determine the angle a sniper must make with his barrel to hit a target over some distance, neglecting air resistance, humidity, etc. Any suggestions as to why my solution on the bottom right is wrong?

Answer was correct. Sometimes all you need is a person to tell you your on the right track. Thanks Doc Al

so after some algebraic manipulation I can solve for m m = 45N --------- g + 1.8N/kg setting "g" to 9.8N/kg yeilds m = 3.88kg So the weight is 3.88kg x 9.8N/kg 38 Newtons!

well weight is equal to mg. An objects mass in kg and the factor of gravity (9.8 N/kg). I'll assume my equation was sound and all your asking is to put in terms of mass. This should yeild me... mg = -m(1.8N/kg) + 45 Idk what you mean friend. I got to thinking and figured that I can...

Soo...(Force on line - Force of gravity) = mass(1.8m/s/s) where the we set the Force on the line to 45 Newtons. The heaviest fish you can pull out of the water at that rate will still be acomplished at 45 Newtons of Tension. The question goes on about how many Newtons gravity will be playing...

Homework Statement A fisherman in a boat is using a "10- test" fishing line. This means that the line can exert a force of 45 without breaking (1lb = 4.45N). If he accelerates the fish upward at 1.8m/s/s , what maximum weight fish can he land, in Newtons? Homework Equations F=ma The...
