Jump Puzzle Velocity

AI Thread Summary

To solve the high jump problem, the initial velocity can be determined using projectile motion equations. The jumper's launch angle of 27 degrees and landing distance of 7.8 meters provide the necessary parameters. Two formulas will be needed to relate the horizontal and vertical components of the motion, as one formula alone results in two variables. The discussion emphasizes the importance of using both horizontal and vertical motion equations to find the initial velocity. Collaboration and sharing of ideas are encouraged to arrive at the solution.

I have a problem. I think that I am just not seeing it the right way. "A high jumper leaves the ground at a 27degrees and lands 7.8 m away. What is the initial velocity. Every formula I have keeps giving me two variables.

Then you need two formulas!

What two formulas do you think will work?

Thread 'Errors and significant figures'

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...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
