Question
Transcribed Image Text:1. A 150 N force acting along an incline is pushing a 6.50 kg object 4.65 m up a 20.0 degree incline. The
coefficient of friction of the incline is 0.268. What will be the speed of the object when it reaches the end
of the incline?
Expert Solution
Step 1
Analyze the free body diagram.
Consider the rightward direction along the incline plane to be positive and the leftward direction along the incline plane to be negative.
From Newton’s 2nd law,
Here, F and Ff represent the pushing force and the friction force, respectively.
The friction force is,
Substitute all the known values in the equation (1).
