AI Thread Summary
To calculate projectile motion in football, the quarterback's throw can be analyzed by breaking the velocity into vertical and horizontal components, using the initial angle of 37 degrees. The horizontal motion can be described with the equation for distance, while the vertical motion involves determining the maximum height and time to reach that height. The initial speed of the ball, time to reach the receiver, and the highest point of the ball's flight can all be expressed in terms of the initial velocity (v) and angle (theta). The discussion highlights the need for substitution to solve for these variables, particularly focusing on the relationships between them. Understanding these concepts is essential for accurately calculating projectile motion in sports scenarios.

Homework Statement


A quarterback throws the football to a stationary reciever who is 40.0m down the field. If the football is thrown at an initial angle of 37.0 degrees to the ground,
a. What is the initial speed of the ball?
b. How much time does it take for the ball to reach the reciever?
c. What is the ball's highest point during its flight.

I took these images from wikipedia... Couldn't figure out that whole LaTeX thing.

The Attempt at a Solution


Well, I didn't get far. I figured you could break the ball's velocity into 2 parts, the vertical motion and horizontal motion, yielding vsin37 for vertical and vcos37 for horizontal motion. However, I don't know what value v is. I'm thinking that substitution will have to be used but I'm not sure where to go from here. I could really use some help! Thanks!

Suppose v is the original velocity... what is the time it takes the ball to get to its maximum height in terms of v and theta? what is the time it takes the ball to get to 40.0m in terms of v and theta?
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
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...
