Projectile Motion in Elevator: Peach Pit Launch Homework

AI Thread Summary
The discussion revolves around a physics homework problem involving projectile motion of a peach pit thrown from a stationary and then an upward-moving elevator. For the first scenario, the time to hit the ground is calculated using the formula t = √(2d/g), yielding approximately 1.498 seconds, with a horizontal distance of about 10.483 meters. The second scenario introduces both horizontal and vertical components of motion, complicating the calculations. The conversation emphasizes the importance of separating the motion into horizontal and vertical components to solve for time and distance. Understanding the appropriate kinematic formulas is crucial for accurately determining the outcomes in both cases.

Homework Statement




A rude tourist throws a peach pit horizontally with a 7.0 m/s velocity out of an elevator cage.
(a) If the elevator is not moving, how long will the pit take to reach the ground, 11.0 m below?
s
(b) How far (horizontally) from the elevator will the pit land?
m
(c) He throws the next pit when the elevator is at the same height but moving upward at a constant 9.5 m/s velocity. How long will it take this pit to land?
s
(d) How far away will this pit land?

The Attempt at a Solution



I am unsure how to approach this, since I don't understand this, what would need tobe done to find time in part1
 
Physics news on Phys.org
Start my splitting the motion into two components, vertical and horizontal motion. Now, considering the vertical motion only, how long will it take the peach to hit the ground?
 
yeah i got part a and b
t=Squareroot(2d/9.8)

and got the "t" to be 1.498sec and multplied the time by 7 and got "b" which is 10.483m
but for the other two it is left me confused, on how to use like forumulas
 
In the previous case, the initial velocity only had an horizontal component, but in the current case the initial velocity has both a horizontal and vertical component. However, the approach is much the same.

Start by splitting the motion into the horizontal components. Which kinematic formula do you think would be appropriate for part (c)?
 
Thread 'Struggling to make relation between elastic force and height'
Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
Thread 'Voltmeter readings for this circuit with switches'
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
