Question

All work for these problems should be in your test for the in-class test, and on your own paper for the retest. Write down relevant equations, draw diagrams and show all of your work and label the different parts for full credit (20 points) A 1.5 kg block of wood is launched up a wooden ramp that has a 40-degree incline. The initial speed of the block is 12 m/s. The coefficient of static friction is 0.4 and the coefficient of kinetic friction is 0.20. Ignore air 1. resistance. Draw the incline with the block at the bottom of the ramp and at the top of its slide. Label with a coordinate system. List all known quantities. B) A) Draw free body diagrams for the block sliding up the incline and down the incline. Label all forces and accleration. c) What is the normal force on the block? D) What is the acceleration as the block moves up the ramp? E) How far up the ramp does the block travel? F) What is the static frictional force on the block when it stops? Is it enough to hold the block there?
