Projectile Motion basketball shot

AI Thread Summary
The discussion focuses on calculating the initial resultant velocity of a basketball shot and the maximum height reached by the ball. The player shoots from a distance of 15 meters at a 55-degree angle, with the hoop height set at 3 meters. Trigonometric principles are suggested for rearranging equations to find the initial velocity. Participants express gratitude for the guidance provided in solving the problem. Understanding projectile motion is essential for accurately determining these values in basketball scenarios.

eek.
I need help.

A basketball player shoots a basketball into a hoop to score a "point". The height of the hoop is 3m. The shooter stands 15 m from the basket and shoots the ball at a 55 degree andle from the horizontal. Assume the height of player is 0.

Need to find:
1) The baslketball's initial resultant velocity.
2) The maximum height of the basketball.

I think you need to use trigonometry and rearrange the equation for the horizontal component (because you have been given it) to get the inital resultant velocity (u).
hope that gives you a start

that helped alot! thanks
 
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...
