How do basketball players jump straight up into the air?

AI Thread Summary
Basketball players jump straight up by exerting force through their leg muscles, which must overcome gravitational force. The key forces at play include gravity pulling the player down and the normal force from the ground pushing them up. Free body diagrams illustrate these forces, showing the balance and interaction between them. The muscle force exerted must be greater than the player's weight to achieve lift-off. Understanding these dynamics is crucial for analyzing the physics of vertical jumps in basketball.

The question asks to describe in terms of physics how basketball players can jump straight up into the air. I also have to show free body diagrams of the forces on the ground and on the player.

The basketball player has gravity and normal forces acting on him and I am assuming that the rest has something to do with muscles, but I'm not completely sure. Any ideas?

How does the force the leg muscles have to exert on the body compare to the player's weight?

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'

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...
