AI Thread Summary
To solve the problem of a baseball passing a window 21 m above the street with an initial speed of 24.66 m/s and a vertical speed of 14 m/s, the next steps involve calculating the maximum altitude the ball reaches and the total time until it returns to the street. The user has already determined that the ball passes the window after approximately 1.09 seconds. To find the maximum altitude, the user can apply kinematic equations that relate initial velocity, acceleration due to gravity, and time. Additionally, to determine when the ball returns to the street, the user needs to calculate the time taken for the ball to descend from its peak altitude back to the street level. Completing these calculations will provide the required answers before the homework deadline.

Homework Statement


A baseball is seen to pass upward by a window 21 m above the street with a vertical speed of 14 m/s. The ball was thrown from the street.

i already found out that initial speed is 24.65806156 and it passed the window after 1.086442406 s.
so, i need to figure out:

What altitude does it reach?
and
After how many more seconds does it reach the street again?

Homework Equations


i don't know.


The Attempt at a Solution


i tryed using the distance formula with my knowns but it i can't get the right answer.

i really need help, this homework is due in a few hours : /

Show what you tried. (How did you solve for the initial speed? A similar method can be used.)
 
Thread 'Collision of a bullet on a rod-string system: query'

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...
