A piece slides down a slippery plane plane slowing from 10 km/h to 5km/h -- what is the friction coefficient?

Click For Summary
SUMMARY

The discussion centers on calculating the friction coefficient for a block sliding on a horizontal plane, starting at a speed of 10 km/h and slowing to 5 km/h over a distance of 23 meters. The participants emphasize the need for a clear diagram or additional details, such as the mass of the block, to apply relevant physics equations effectively. The primary equations involved include those related to kinetic friction and deceleration, which are essential for solving this problem accurately.

PREREQUISITES
  • Understanding of Newton's laws of motion
  • Familiarity with the concept of kinetic friction
  • Knowledge of basic kinematics equations
  • Ability to manipulate algebraic equations
NEXT STEPS
  • Learn how to calculate the friction coefficient using the equation: μ = F_friction / F_normal
  • Study kinematic equations to relate initial velocity, final velocity, acceleration, and distance
  • Explore the concept of work-energy principle in physics
  • Understand how to derive acceleration from velocity changes over time
USEFUL FOR

Students studying physics, educators teaching mechanics, and anyone interested in understanding the principles of motion and friction in real-world applications.

I presume there was a diagram, or maybe just a rather more informative description.

At a guess, the set up is:
"A block slides on a horizontal plane. It starts at speed 10km/h, but friction reduces this to 5km/h over a distance of 23m."

Per forum rules, you need to show an attempt.
What standard equations have you been taught that may be relevant?

"A block slides on a horizontal plane. It starts at speed 10km/h, but friction reduces this to 5km/h over a distance of 23m." This is all what is stated in the assignment. I would have solved if the mass had been told ..

So let the mass be m and see what happens.
 

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?
