Reference Example 4.5 in your book. Gravity is modeled as a constant acceleration of 9.80 m/s2 downward. Free-body diagram A 65.0 kg skier slides along a θ-31.5° slope as shown. The slope exerts a frictional force off-66.6 N. What is the skier's acceleration down the slope? m/s How strong is the Normal force exerted by the slope? N.

A skier with mass 64.0 kg starts at rest at the top of an 842 m long ski slope, which makes an angle 13.0 ∘ with the horizontal. A typical coefficient of friction between skis and snow is 5.20×10−2. skiers don't go straight down the hill- they zigzag back and forth. Even though they still end up at the bottom of the hill, they've lost more energy to friction because friction is a non-conservative force. Let's say due to zigzagging,...

Question 3: In order to determine the force of friction and the coefficient of kinetic friction, you will use Vernier Video Analysis to find the acceleration of the cart. You will use the following video to determine these values. Download the following video and open up Vernier Video Analysis, and then import the video into the program. You need to begin your analysis after the hand is no longer pushing the cart and finish when the cart has come to...

A lawnmower (mass m) is being pushed on rough ground (so there is friction) down a slope. The slope is at an angle theta_1 with respect to level ground and the force applied to the lawnmower makes an angle of theta_2 with respect to the slope as drawn. Draw an accurate force diagram labeling all the forces acting on the mower. Using the x and y coordinates given (+x down the slope and +y up perpendicularly from the slope) write...
