You and your friends push a 75.0 kg greased pig up an aluminum slide at the county fair, starting from the low end of the slide. The coefficient of kinetic friction between the pig and slide is 0.070.

(a) All of you pushing together (parallel to the incline) manage to accelerate the pig from rest at the constant rate of 5.0 m/s ² over a distance of 1.5 m, at which point you release the pig. The pig continues up the slide, reaching a maximum vertical height above its release point of 45 cm. What is the angle of inclination of the slide?

(b) At the maximum height the pig turns around and begins to slip down the slide, how fast is it moving when it arrives at the low end of the slide?
