Kinetic and Potential Energy of Baseball Graphing Question

AI Thread Summary
The discussion focuses on graphing the gravitational potential energy of a baseball thrown upward and caught after 5 seconds. It highlights that the potential energy graph is the inverse of the kinetic energy graph, as total energy remains constant in the absence of air resistance. As the baseball rises, its kinetic energy decreases while potential energy increases, and vice versa when it falls. Understanding this relationship is crucial for accurately sketching the potential energy graph. The key takeaway is that the two energy types are interconnected, reflecting the conservation of energy principle.

A baseball is thrown directly upward at time t=0 and is caught again at time t=5\;\rm s. Assume that air resistance is so small that it can be ignored and that the zero point of gravitational potential energy is located at the position at which the ball leaves the thrower's hand.

I need to sketch a graph of the baseball's gravitational potential energy. I am stuck at this part. I already did the graph for kinetic energy but I do not know what to do for this

If, as you say, you already have the kinetic energy graph, then the potential energy graph is the exact inverse of it. This is because the total energy (k.e. + p.e) is constant. As the one goes up the other goes down such that the sum stays the same.
 
thank you
 

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...
