hey, so my physics teacher gave us an assessment today, basically everyone got 2 different questions, and we have to solve them and explain our work, and im having trouble with them. i missed a good chunck of one section, and of coure, thats the section my questions came from. im not asking anyone to do my work, but if someone who gets physics is bored, could you maybe help me out by doing it out and comparing answers? anyone who helps gets a hefty 10/10.
1. Determine the minimun angle at which a roadbes should be banked so that a car traveling at 10.0 m/s can safelt negotiate the curve if the radius of the curve is 2.00 x 10^2 m.
2.What is the acceleration due to gravity at an altitude of 1.00 x 10^6 m above the earth's surface? NOTE: the radius of the earth is 6.83 x 10^6 m.
i had some trouble with number one because i never took a calc class, so im stuck with tan(theta) on one side and i dont know what to do. any help at all is greatly appreciated.
