A string is tied to a box that weighs 175 N. The string is angled in the direction 30.0◦ above the horizontal and used to pull the box across a rough horizontal surface with increasing speed. The tension in the string has a magnitude of 150 N and the coefficient of kinetic friction between the block and the surface is µk = 0.500. (a) Draw the free-body diagram of the box. Make sure you label all your vectors and clearly indicate their direction. (b)What is the magnitude of the normal force exerted on the box by the surface?
Homework Answers
normal force exerted on the boc by the surface
N = W - T sin x
N = 175 - 150* sin 30
N = 100 N
