Three blocks each of mass 12 kg are on the frictionless, Ask an Expert

Academics

Q1. Three blocks, each of mass 12 kg are on the frictionless table. A hand pushes on the left most box (A) such that the three boxes accelerate in the positive horizontal direction as shown at a rate of a = 1.1 m/s2. What is the net horizontal force on block B?

Q2. A 60kg skier slides down a hill inclined at 42 degrees. The coefficient of friction on the hill is 0.1. If the skier starts with a speed of 2 m/s and slides for 110m, what final speed would the skier achieve?
