Question
Consider a skier heading down a 11° slope. Assume the coefficient of friction for waxed wood on wet snow is μk = 0.10 and use a coordinate system in which down the slope is positive.
a. Calcuate the magnitude of the acceleration of the skier in m/s2
b. Find the angle, in degrees, of the slope on which this skier could move down the slope at constant velocity

However, the return journey takes 2 hours. Calculate the V and V₁. Hint: Velocity = displacement/time. Displacement can be positive of neagtive depending on the direction. You will first need to set up the equations by taking into account the resultant velocity of the boat in flowing water. Consider the direction the river is flowing to be positive. Set up two equations, one for the downstream journey and one for the upstream journey, in terms of "V" and "v": Do V" and "v, add or substract downstream to give the resultant downstream velocity? Do v" and "v, add or substract upstream togive the resultant upstream velocity? Use the upstream direction as negative. The resultant upstream velocity should be negative.
