Answer Happy

Give all numerical answers to three (3) significantfigures.
Problem 4: (20 points) A 30-kg crate is placed on a ramp, which is inclined 50° above the horizontal as shown below. The kinetic friction is 76. When the crate is released from rest, it slides down the ramp. When it reaches the bottom of the ramp, it is traveling at 1.56 m/s. 50° v = 1.56 m/s a) (10 points) Draw a free-body diagram for the crate, showing all forces that act on it. Label all forces, and show their directions. b) (10 points) Find the acceleration of the crate as it slides down the ramp.
