1. Imagine a skier sliding down a hill. Draw a simplified "stick figure" type sketch of the situation, and a free-body (force) diagram of
the skier by hand. Assume for now that there is no friction between the skis and the hill.
Use a ruler! Make sure that your axes and force vectors are straight lines and draw your force vectors proportional to their
magnitudes. You can take a picture of your force diagram with your phone and upload it using the image upload tool on the menu
above your answer box.
1. the normal force on an object by a surface is always perpendicular to the surface.
2. the force of gravity is always directly downward.
Hint:
3. use the particle model to represent the skier as a "dot"
4. Label your coordinate axes and the forces
5. Use the parallelogram rule to show the net force acting on the skier. Which way does it point? Is that where it should
point? If not adjust the lengths of the force vectors so that their sum points in the direction of the acceleration!
2. Two masses were connected by a frictionless pulley and is placed in an inclined plane with kinetic friction coefficient of 0.2. If we let mass m2 to move at a constant speed downwards, give the following:
a. Draw the FBD and write the summation of all forces acting
on the masses.
b. Solve for mass m2 if mass mı = 4kg.
c. Find the tension force of the string.
Choose ONE of the following problems to solve!!
1. Andrew (m = 60.0 kg) is skiing down a hill of incline of 27.0°.
There is a force of friction acting on him of 45.0 N.
a) Draw an FBD and choose an appropriate coordinate system.
b) Determine the normal force on Andrew.
c) Determine the net force along the ramp and the acceleration
down the hill.
