hmm yes I think that may be part of it. I still just don't feel totally satisfied with that answer. I just feel as though something is missing. maybe I am just trying to complicate the matter.

Homework Statement Newton's Principia suggested that if you fire a cannon from a high mountain it could fall, circle the earth, or fly away depending on how hard it was fired. Describe how this compares to bullet trajectories. What is the major difference with this trajectory? (for...

sorry does anyone else have any ideas... the last few replies have been cryptic and short

Sorry that was a typo... I fixed it ... they land with the same final velocity.

Hey tiny-tim... It does say in part b of the question that the would indeed hit at the same speed...

okay ... so a) The angle of the projectile does not matter since the angle does not change the amount of energy that the rock possesses. b) and to justify the conservation of energy would be: The sum of the potential and kinetic energy at launch is: Ei = PE +KE - mghcliff + 1/2mv12...

Homework Statement I have been given this example with the following questions: 1. Two rocks are thrown off of a cliff with the same initial speed, v. The first rock is launched with at an angle Ө directed below the horizontal as shown below as 1, while the second rock is launched above at the...

So I am again stuck on a question I have been provided. The question is: Draw a FBD for each monkey. For each monkey, determine the rope tension that would allow the monkey to begin accelerating in the expected direction. (on a side note this is a pulley situation one monkey is 22kg and the...

Thank you! that absolutely clears things up.

Okay So, the question I have here is.. Masses are connected as shown. m1 = 5.0 kg and m2 = 4.0 kg. a) find the acceleration of each object and b) the tension in the two strings I have attached the picture example as well (as there is another unlisted weight in it) With pulley problem's I...

a yes... so you see my frustration's with my course... I realize this graph does not match what is being asked, and since my teacher is on winter break I can not ask her why. My plan is to just use this graph (which was the one provided for the question) and just solve for the graph... not for...

Hello, Again I find my self struggling on a question I had on a test, as my teacher is a "general studies" teacher, she is not much help with physics. the question is: What is the average speed of the car for the 10 second interval? I have uploaded the graph provided, if you can't...

The answers are provided from my teacher, I was wondering as well if the answers provided where correct. I had a sneaky suspicion that they where not, as I do not normally struggle this bad on a question like this. Maybe I will just confirm with my teacher, before I get anymore into the...

Okay So I took you guys advise and i did as follows: vy = vo - 2at where a is equal to negative gravity vy = 83.14 m/s - 2(-9.81m/s2)(2s) Vy = 122.34 Vx = Vo - 2at where the vertical acceleration is 0 Vx = 48 m/s - 2(0)(t) Vx = 48 m/s tan ° = 48/122.34 tan-1+ tan-1°=...

Sorry, I might be a little simple, but I only have the four main equations infront of me and I just can't figure out what one to use. and how do I use a kinematic equation to get a degree answer??
