Thinking about the winter we missed out on this year. Calvin and his tiger go sledding down a snowy hill. There is friction between the snow and the sled, and there is air resistance. Looking at the entire time that they spend on the hill (from when they start from rest at the top of the hill until they reach the bottom moving fast), indicate whether each of the following quantities is positive, negative, or zero, by writing either +, -, or 0 for the questions below. We take Calvin, the tiger, and the sled as our system.

a)The work done by the normal force that the snow exerts on the system

b)The work done by the frictional force that the snow exerts on the system

c)The change in the kinetic energy of the system

d)The change in the gravitational potential energy of the system

e)The total work done on the system
