It's been a while since I've been in a math class. I'm just trying to make a simple openGL demo, and I ran into this problem. If you look at the picture, I know the values of: x, y x', y' θ Now, from those, how can I find X2' and Y2' on a cartesian coordinate system? lol, the...

I gave it some more thought, and here's what I got (some help from another friend). a) calculated acceleration with a = v/t formula. Then used that a to find the netforce Fnet = ma. The accleration was 65000 m/s^2 (whoa!) and the netforce was 2925 N. b) The golf ball leaves the club...

A) I thought there'd be a different method of doing it because we haven't learned about impulse forces or that formula yet. We are doing circular motion now, so I thought this releates to that. Beside, the golf club is swang at a semi circular motion so I thought that'd be it. b) You neglect...

The problem is we haven't got to momentum and impulse yet. We are still doing basic grade 12 motion in 2d, and recently started circular motion for the first time. So there's got to be an easier way out :(

High-speed movies reveal that the time interval during which a golf club is in contact with a golf ball is typically 1.0 x 10^-3 s and the speed of the ball when it leaves the club is about 65 m/s. The mass of a golf ball is 0.045 kg. a) Determine the magnitude of the average force exerted...
