SUMMARY

The discussion centers on solving a physics problem involving a seal with a mass of 82 kg that jumps onto a horizontal ice float with an initial velocity (Vo) of 6 m/s. The frictional force acting on the seal is 160 N, leading to a calculated acceleration of -1.95 m/s². Participants suggest using the work-energy equation to determine the distance the seal slides on the ice after the jump.

PREREQUISITES
  • Understanding of Newton's second law (F=ma)
  • Knowledge of frictional forces and their calculations
  • Familiarity with the work-energy principle
  • Basic concepts of kinematics
NEXT STEPS
  • Study the work-energy theorem in detail
  • Learn how to apply kinematic equations to solve for distance
  • Explore examples of frictional force calculations in physics
  • Review problems involving acceleration and deceleration
USEFUL FOR

Students studying physics, educators teaching mechanics, and anyone interested in applying physics concepts to real-world scenarios.

Hello there, I am having trouble with this question:

A seal, mass of 82kg, jumps onto a horizontal ice float with a Vo of 6m/s i. The friction between the seal's belly and ice is 160N. g is 9.81m/s^2. How far does the seal slide?

So so far, if I'm correct, I calculated the acceleration:

Fnet=ma (i)

a= Ffriction/mass

a=-160N/82kg=1.95m/s^2.

And now I'm stuck. Do you need to find the time?

Hello einsteinette! :smile:

Use the work-energy equation … work done = change in energy. :wink:
 
Ahh! Ok thanks! I get it now!
