AI Thread Summary
To calculate the height of a basketball player's jump based on a jump duration of 0.80 seconds, the time can be divided into upward and downward phases, each lasting 0.40 seconds. The relevant equation of motion, s = ut + 0.5at^2, can be applied, where 'u' is the initial velocity, 'a' is the acceleration due to gravity (approximately -9.81 m/s²), and 't' is the time. By substituting the values into the equation, the maximum height can be determined. The discussion emphasizes the need to clarify the acceleration value and the initial velocity for accurate calculations. Understanding these principles is crucial for solving the problem effectively.

Homework Statement



a basketball player jumped straight up to grab a rebound. if she was in the air for 0.80 second how high did she jump?

Homework Equations



i know the time but i don't know which equation to use

The Attempt at a Solution



i don't know how to solve yet
 
Physics news on Phys.org
0.8 = time to go up(t1) + time to come down(t2)

t1 = t2 = 0.8/2 (should be right)

vertical distance traversed use equation of motion

s = ut + 0.5at^2

can you go on from here?
 
Try s = 0.5 a t2, where a is the acceleration.
Given the time and acceleration (what is it?) you can find the largest distance (which is the top of her jump).
 

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...
