Question: Under the influence of gravity, a block slides down a slope inclined at an angle theta to the horizontal. The coefficient of dynamic friction

Under the influence of gravity, a block slides down a slope inclined at an angle \theta to
the horizontal. The coefficient of dynamic friction is k.
i) Draw a free-body diagram for the block.
ii) If k =0.5, find the value of \theta for which the block moves at constant velocity..
