SUMMARY

The discussion focuses on calculating the velocity of a truck weighing 6000 lb as it navigates a curve with a radius of 650 feet, given a maximum friction force of 1125 lb. The solution involves applying the principles of centripetal acceleration and Newton's second law, leading to the formula F = ma, where the friction force equals mass times centripetal acceleration. The final calculated velocity is approximately 11.04 ft/s.

PREREQUISITES
  • Centripetal acceleration concepts
  • Newton's second law of motion
  • Unit conversion between pounds and kilograms
  • Understanding of circular motion dynamics
NEXT STEPS
  • Study centripetal force calculations in circular motion
  • Explore advanced applications of Newton's laws in physics
  • Learn about friction coefficients and their impact on vehicle dynamics
  • Investigate real-world examples of vehicle handling in curves
USEFUL FOR

Students preparing for physics exams, particularly those focusing on mechanics, as well as educators teaching concepts of motion and forces.

A truck weighs 6000 lb. The truck is going around a curvewith a radius of 650 feet. The maximum friction force the road can exert on the tires is 1125 lb. it wants me to calculate the velocity in ft/sec

I am sort of lost on this an y help would be great

thanks

Think about centripetal acceleration & centripetal force.

What is needed to keep the truck moving along that curve, and what can the road provide?
 
still having problems

right now the only thing I know what to do is I converted the items that are in pounds to Kg. and feet to m

struggling
 
OK, centripetal acceleration is given by v^2/r.

And by Newton's second law, we know that F=ma. Since the car is moving in a circular path, he is accelerating. The only force that is pointing towards the center of the circle is friction. So:
F=ma
Force of friction = m*(v^2/r)
1125lb = 6000lb*(v^2/650ft)
v=11.039701082909808568455053408699 ft/s

thanks a lot i have been trying to catch up on all the homewok and study for my physics final

thanks again
 

Thread 'Magnitude of buoyant force in fluids of different densities'

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
