A projectile is shot from the edge of a cliff h = 125 m above ground level with an initial speed of v0 = 115 m/s at an angle of 37.0° with the horizontal.

Determine the time taken by the projectile to hit point P at ground level. (time in seconds)

Determine the range X of the projectile as measured from the base of the cliff. (Distance in km)

HI,
I am from the United States and I wanted the names of any medications you know of or take for IBS and abdominal/stomach pain. I have read about some that are from other countries...(like Buscopan or Colpermin can they be purchased in the US?)
Please list any medications that help IBS that are in the US! thank you so much

This quote is from "Good Will Hunting":

-Have you studied organic chemistry?
- A little bit.
- Oh, just for fun?
- Yeah, for kicks.
-Yeah, it's so much fun
studying organic chemistry.
- Are you mad?
- [ Laughs ]
-Have you completely
lost your mind?
Nobody studies it for fun.
It's not a necessity,
especially for someone like you.
- Someone like me?
- Yeah.
-Someone who divides their time, fairly
evenly, between batting cages and bars.
- I would hardly say it was a necessity.
- Oh.
-You know, there are very
smart people here at Harvard.
Even they have to study,
because this is really hard

I didn't pursue a medicine or biology career, I'm a Computer Scientist. However, I have a strong interest in exploring the internals of the human being, looking at the organs from a close distance, look at an opened skull with the brain and eyes connections exposed, the lungs, hearth, the prostate and the conduits to the testicles, and so on. I know I cannot go into a lab without any permission, so I would like to know what can I do about it. Is there any place where you can go to see an human being and its elemental parts? (I already saw pigs, just in case)

A small button placed on a horizontal rotating platform with diameter 0.322 m will revolve with the platform when it is brought up to a rotational speed of 35.0 rev/min, provided the button is a distance no more than 0.160 m from the axis. The coefficient of static friction between the button and the platform is 0.219.

How far from the axis can the button be placed, without slipping, if the platform rotates at 64.0 rev/min?

Take free fall acceleration to be g = 9.80 m/s^2.

Thanks for the help!

Whats the equation to calculate the mechanical advantage and efficiency of pulleys? How would I do it if I have the weight of the object used, the amount of force used in Newtons and the length of the string used to lift the weight. How do I calculate the ideal mechanical advantage?
