October 7 physics In: A 3 kg book slides In: A 3 kg book slides across a table and decelerates to a stop. The acceleration is 5 m/s2. What is the force of friction on the table? What is the µ of the table/book combination? Objective:
Objective: To Show our understanding of the force of friction and Newton’s laws by taking a quiz.
Success criteria: To be able to solve friction equations using Ff Fn and μ A glacier has a mass A glacier has a mass of 5x1010 kg and moves at a constant
velocity of .5 m/day.
If the force of friction between glacier and rock is .2, what is the force of friction scraping the rock below the glacier? Three kids paddle a boat forward with a Three kids paddle a boat forward with a combined force of 200 N. The water resists the motion with a force of 100 N. The mass of kids and boat is 150 kg. Draw a free body diagram, and figure out the acceleration of the boat. Quiz
