Nevermind, i know what i was doing wrong, i was drawing my triangles wrong.

Im studying for a test tomorrow and I'm doing a question, which someone posted the answers to on here in another topic i did it and got the wrong answer apparently can someone check and make sure I am not messing up? A pulley device is used to hurl projectiles from a ramp (mk = 0.26) as...

Well i ended up completing the question, i ended up just going to my teacher for help. i can see why it was so hard for it to be explained xD there's a lot u have to do and i was on a totally different track. Thanks for the help though Delphi51 :)

anytime, Glad i could help, don't forget to convert to g's, the conversion factor is: 1g = 9.81 m/s^2 basically 1g is the acceleration of gravity

okay i officially hate this problem. I am playing with a triangle diagram for Fn and Ff, and I am using Ffx + Fnx = mv^2/r Ffx = mv^2/r - Fnx so then i got got a formula for fnx tan theta = fnx/fny tan theta = fnx/mg because fny = Fg and Fg = m(9,81) therefore, Fn = tan theta (mg) so then i...

Thats right. so you have v1, v2, and t, and your looking for acceleration so what formula has all of those variables in it

Would i be safe to assume a mass in order to solve for the gravitational force down?

Well Hes starting with a speed and he's comming to a stop.

okay so you have time, and velocity and your looking for acceleration. But Velocity can be split into V1(Initial) and V2(Final) so what was his initial velocity and final velocity?

What are your givens and your requirements. Writing those down makes finding the correct formula to use easier

Im pretty sure (correct me if I'm wrong) but this forum is for help on a question not the answer, what exactly are u struggling with?

Okay so i have a test and so I'm reviewing for it, and one of the questions i came across was: 1. A curve of radius 180 m is being designed in a new highway to allow cars traveling at 70 km/h to round the curve with zero frictional forces. a) At what angle must the road be banked? b) What is...
