Homework Help Overview

The discussion revolves around two physics problems involving concepts of friction, acceleration, and motion on curves and slopes. The first problem concerns a car navigating an unbanked curve, while the second involves a person sliding down a slope.

Discussion Character

  • Mixed

Approaches and Questions Raised

  • Participants express confusion regarding the appropriate equations to use for solving the problems. Some mention the need to understand centripetal acceleration and lateral frictional forces in the context of the car problem. Others highlight the importance of identifying the correct approach for calculating acceleration down the slide.

Discussion Status

The discussion is ongoing, with participants seeking clarification on the equations and concepts involved. Some have attempted to engage with the problems but express uncertainty about their understanding and the necessary steps to take.

Contextual Notes

Participants are reminded of forum rules requiring the posting of attempted solutions and relevant equations, which has led to some hesitation in progressing with their inquiries.

on his way home from the office, stevens car rounds an unbanked curve that has a radius of 100 m. if the coefficient of friction between the tires and the road is 0.40, what is the fastest speed at which the car can round this curve in miles per hour?

i tried to solve but i just do not understand
 
Physics news on Phys.org
this is another problem i need help with

Madison, whose mass is 35.0 kg, climbs the ladder on the slide in her back yard, and slides to the ground at an angle of 30.0⁰ to the horizontal. If the coefficient of sliding friction is 0.15, what is Madison’s acceleration down the slide? Ignore the initial effects of starting friction.
 
per the rules you need to post up the equations your trying to use and your attempt at a solution
 
i do not know what equation I am supposed to use and i hvnt attempted to solve due to me not knowing that
 
my second problem has to do with friction and slope
 
If the car has speed v, what centripetal acceleration is needed to make it around the curve? If m is the mass of the car, what lateral frictional force does that imply?
(Pls use a separate thread for unrelated problems.)
