1)A 25 kg block of salt is pulled across a floor by a rope with a force of 75N.
a)Draw a quantitative(with numbers)free body diagram for the force acting on the block?
b)Calculate the force of friction acting on the block if the coefficient of friction between block and floor is 0.21? (PLEASE SHOW ALL WORK WITH UNITS)
c)Calculate the acceleration of the block(Hint: think Fnet)? (PLEASE SHOW ALL WORK WITH UNITS)
2)A spring scale is used to pull a 19 kg cart across a piece of sandpaper at a constant speed with a force of 25N.
