A crate of weight W is being pushed across a horizontal surface bya force directed at an angle of 20 degrees below the horizontal.What is the magnitude of the normal force on the crate?
a) it is less than W
b) it equals W
c) it is more than W
d) none of the above since the coefficient of kinetic friction isnot given
