r practice: friction and energy worksheet

ow it connects to amperes, faradays, and magnetic dipoles and need help with proofreading and correcting what I have so far.

s for the exam next week so step by step plz

ated formula show the picture and box the answer. Also, Don't forget the unit. also, please please show detailed work including very small calculation such as plus and minus. please also clear all the steps so i can use it as example for the similar questions Thank you.

e answers to them as well) given by the teacher. I need a tutor to talk these problems outloud with me and help me study.

hem on a sheet to show prior I need live help more of to go over the questions to make sure i got them right

it is general physics associate college level

goal is to look to 1) at the fractal nature of the turnover time as a function of initial conditions such as https://en.wikipedia.org/wiki/Double_pendulum#Chaotic_motion. 2) calculating the Lyapunov exponent of the system by looking at separation times of very close initial conditions. Can you help me with this project? I have very limited knowledge on Matlab.

A. The answer is 3C/5. I only need help with part B. Thank you.

n, I completed parts A and B, but can't get C. We get all the answers to the questions but not how to get to the answer. The question is: Patrick changes velocity from 2.0 m/s North to 4.0 m/s South with an acceleration of 0.50 m/s/s South. (A) Determine how much time this process takes (ANSWER: 12 s). (B) Find his displacement (magnitude and direction) (ANSWER: 12 m South). (C) Find how much distance Patrick covered (ANSWER: 20 m). Another question I was having trouble with was this (I got part A but not parts B or C): Two cars are traveling along a straight line in the same direction, the lead car at 25.0 m/s and the other car at 30.0 m/s. At the moment the cars are 40.0 m apart, the lead driver applies the brakes, causing his car to have an acceleration of -2.00 m/s/s. (A) How long does it take for the lead car to stop? (ANSWER: 12.5 s). (B) Assuming that the chasing car brakes at the same time as the lead car, what must be the chasing car's minimum negative acceleration so as not to hit the lead car? (ANSWER: -2.29 m/s/s). (C) How long does it take for the chasing car to stop? (ANSWER: 13.1 s).
