Question
A box of unknown mass is 5 meters up a frictionless ramp and is let go from rest. Assume the
ramp has an angle of ? = 30°.
a) Set your positive x axis so that it goes down the ramp. Draw the free body diagram for the
box. In the free body diagram, indicate both the x and y components of the Weight.
b) What is the acceleration of the block?
c) What is the velocity of the box when it reaches the bottom of the ramp (hint: use a 1D
d) How much time does it take to reach the bottom of the ramp (hint: again, use a 1D kinematic
equation).
