AI Thread Summary
To calculate the horizontal distance a rescue plane's package travels before hitting the ground, first determine the time it takes for the package to fall from a height of 45.0 m. Using the formula for free fall, the time can be calculated as approximately 3 seconds. With the plane traveling at a horizontal speed of 75.0 m/s, the horizontal distance can then be calculated by multiplying the time of fall by the horizontal speed. This results in a total horizontal distance of about 225 meters before the package strikes the ground. Understanding these calculations is essential for accurately determining the drop distance in rescue scenarios.

1. A rescue plane drops a package of emergency rations to a stranded party of explorers. The plane is traveling horizontally at 75.0 m/s at a height of 45.0 m above the ground. What horizontal distance does the package travel before striking the ground?

Welcome to PF.

What are your thoughts on how to approach the problem?
 
I don't know I really can't even figure out where to start.
 
Start maybe with figuring out how long it takes to fall?

If you know that then maybe you can figure out from the horizontal speed how far along it hits the ground?
 
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 'Minimum mass of a block'
Here we know that if block B is going to move up or just be at the verge of moving up ##Mg \sin \theta ## will act downwards and maximum static friction will act downwards ## \mu Mg \cos \theta ## Now what im confused by is how will we know " how quickly" block B reaches its maximum static friction value without any numbers, the suggested solution says that when block A is at its maximum extension, then block B will start to move up but with a certain set of values couldn't block A reach...
