A light inextensible rope is used to pull a particle of mass 3 kg along a rough horizontal plane. The tension in the rope is 15 N and acts at an angle of 40° above the horizontal.
If the coefficient of sliding friction between the particle and the surface is 0.45, what is the acceleration of the particle?

The desk has a weight of 75 lb and a center of gravity at g. determine the initial acceleration of a desk when the man applies enough force f to overcome the static friction at a and b. also, find the vertical reactions on each of the two legs at a and at b. the coefficients of static and kinetic friction at a and b are ms = 0.5 and mk = 0.2, respectively

Why don't you see your reflection in water with waves or repples
