Question: A penguin slides at a constant velocity of 1.55 m/s down an icy incline. The incline slopes above the horizontal at an angle of 7.08°. At the bottom of the incline, the penguin slides onto a horizontal patch of ice. The coefficient of kinetic friction between the penguin and the ice is the same for the incline as for the horizontal patch.
Part A: How much time is required for the penguin to slide to a halt after entering the horizontal patch of ice?
Please give me an explanation for above question.
