- Find the mass of the painting. The tension in the leftmost rope is 7.2 N, in the middle rope it is 16 N, and in
the rightmost rope it is 16 N. - Find Brittany’s acceleration down the frictionless waterslide in terms of her massm, the angleθof the incline,
and the acceleration of gravityg. - The physics professor holds an eraser up against a wall by pushing it directly against the wall with a completely
horizontal force of 20 N. The eraser has a mass of 0.5 kg. The wall has coefficients of frictionμS= 0 .8 and
μK= 0. 6.
