Vertical Jump Time Calculation for Basketball Player

AI Thread Summary
A basketball player jumps 74.7 cm vertically, and the discussion focuses on calculating the time spent in the top and bottom 10.6 cm of the jump. The user initially calculated the final velocity as 3.83 m/s but struggled with the application of the equations of motion due to a lack of clarity on initial velocity (v0). Other participants suggested identifying the known data and clarifying the variables used in the calculations. The user expressed concern about limited attempts to solve the problem correctly. The discussion emphasizes the importance of understanding the equations and the variables involved in the calculations.

Homework Statement


1.A basketball player, standing near the basket to grab a rebound, jumps 74.7 cm vertically.
A) How much time does the player spend in the top 10.6 cm of his jump?
B)How much time does the player spend in the bottom 10.6 cm of the jump?

Homework Equations


1)v=v0 + at
2)x-x0=v0*t -.5at^2

The Attempt at a Solution


I solved for V=3.83 m/s then i substituted that into the second equation and came out with time spent at top=.0287s and at the bottom=.753s

I only 3 more tries to get the problem right but I am trying to figure what I am doing wrong and how to solve it.

I'm afraid you'll need to give more details of your attempt. How did you manage to "solve for v"? Both of the equations you mention need a v0, and I don't see one in your data...

It would perhaps help if you identify what data you have been given in the question (i.e., name it –*this number is an acceleration, that one is an initial velocity) and what you want to find out.
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
Thread 'A cylinder connected to a hanged 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...
