Question

A 3.5 kg block is pushed
along a horizontal floor by a force
of magnitude 15 N at an angle
40 with the horizontal
. The coefficient of kinetic
friction between the block
and the floor is 0.25. Calculate the
magnitudes of (a) the frictional
force on the block from the floor
and (b) the block’s acceleration.
