Q1. The coefficient of static friction between the block and table's surface is &mu s = 1/3. The mass of the block that is hanging down is n1 Kg. The tangent of the angle shown in the figure is tan & theta = n2. What is the minimum value of mass, n3 Kg that the block on the table can have such that system is in equilibrium.
Q2. A truck with a mass of 804.88 kg has an initial momentum of -2444.80 kg*m/s and the final momentum of -8639.48 and experiences an impulse of -6195.86 N*s.
what's the truck's final velocity?
