SUMMARY

The discussion focuses on calculating the final velocity of a 0.160-kg hockey puck subjected to two different forces over a time interval of 5.5×10-2s. When a force of 24.0N is applied to the right, the puck's velocity increases from an initial speed of 2.98m/s. Conversely, applying a force of 12.5N to the left results in a decrease in the puck's velocity. The key equations involved include Newton's second law and the kinematic equations for motion.

PREREQUISITES
  • Understanding of Newton's second law of motion
  • Familiarity with kinematic equations
  • Basic knowledge of vector forces
  • Concept of momentum and impulse
NEXT STEPS
  • Study the application of Newton's second law in various scenarios
  • Learn how to calculate impulse and its effect on momentum
  • Explore kinematic equations for one-dimensional motion
  • Investigate the effects of friction on motion in real-world applications
USEFUL FOR

Students studying physics, particularly those focusing on mechanics, as well as educators seeking to enhance their understanding of force and motion concepts.

Homework Statement


A 0.160-kg hockey puck is moving on an icy, frictionless, horizontal surface. At t=0 the puck is moving to the right at 2.98m/s .

Homework Equations



Calculate the magnitude of the velocity of the puck after a force of 24.0N directed to the right has been applied for 5.5×10−2s .
If instead, a force of 12.5N directed to the left is applied from t=0 to t= 5.5×10−2s , what is the magnitude of the final velocity of the puck?
