2. Look at the diagram shown below.

Keith

Carl

Keith and Carl are taking part in a marathon. Carl seems to have more difficulty running than Keith. Why is that so? (1) Gravity is hindering Carl up the slope but helping Keith down the slope.(2) Carl is not as fit as Keith in terms of stamina.(3) Frictional force is acting against Carl but not Keith.(4) There is gravitational force acting against Carl but not Keith.
