Q1. A 51-kg person on skis starts from rest down a hill sloped at 32° from the horizontal. The coefficient of friction between the skis and the snow is 0.12. After the skier had been moving for 5.0 s, the friction of the snow suddenly increased and made the net force on skier zero. What is the new coefficient of friction?

Q2. In outer space, far from other objects, block 1 of mass 30 kg is at position < 12, 8, 2 > m, and block 2 of mass 1350 kg is at position < 19, 8, 1 > m. What is the (vector) gravitational force acting on block 2 because of block 1? It helps to make a sketch of the situation.
