How Do You Calculate the Net Force and Angle in Vector Addition?

AI Thread Summary
To calculate the net force on the ball kicked by two players, one exerting 58 N west and the other 75 N south, the forces can be represented as a right triangle, leading to a net force of 95 N. To determine the angle of the resultant vector, trigonometric functions such as tangent can be used, with the angle options being S 52° W or 38°. The discussion emphasizes the importance of using specific trigonometric formulas to solve for angles in vector addition. Participants suggest that drawing the vectors and applying trigonometry is crucial for accurate calculations. Understanding these principles is essential for solving similar physics problems effectively.

1. Two soccer players kick a ball at the same time. One player exerts a force of 58 N west and the other student exerts a force of 75 N south. What is the net force on the ball?



2. V= Vf-Vi, trig formulas



3. i drew this question out and it made a right triangle, so i solved for the hypoteneuse which was 95 [N]. however, i don't know how to figure out the angle. This question is multiple choice, so it's either S 52o W or 38o

When you say "trig formulas", be more specific. That's a hint, BTW.
 
Good hint turin. dance_sg you're on the right track thinking of trigonometrey to find the sides...whaddya know about angles?

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
