Question
A penguin starts from rest and accelerates across the snow at a constant rate until he hits the ice, as depicted in the figure below. He then throws himself down and begins to slide along on the frictionless ice. He then goes over the edge into an ice gully and slides up a vertical ice cliff on the other side. Speeds up to here then starts sliding Highest point. that he reaches Starts at rest D Snow Ice F a) Draw a curved line on your paper that represents the shape of the snow and ice (you don't have to draw the penguins). Add points to your drawing that are like the labeled points above. Along your line, draw an arrow to represent the penguin's veloc- ity at each of the labeled points, including roughly scaling the lengths of the velocity vectors to represent the penguin's speed at each point. If it is zero at any point then write "v = 0" by the point. b) Draw arrows to represent the direction of the penguin's acceleration at each of the labeled points. If the acceleration is zero at any of these points, then write "a = 0" by the point.
