A toboggan is sliding down a snowy slope. The table shows the speed of the toboggan at various times during its trip. (a) Make a graph of the speed as a function of time. (b) Judging by the graph, is it plausible that the toboggan’s acceleration is constant? If so, what is the acceleration? (c) Ignoring friction, what is the angle of incline of the slope? (d) If friction is significant, is the angle of incline larger or smaller than that found (c)? Explain.

1. if the speed vs time is a straight line, acceleration is constant.

c) acceleration=g*cosTheta

d) if riction is significant, the angle has to be larger.
