A 116 kg seal at an amusement park slides from rest down a ramp into the pool below. The top of the ramp is 1.85 m higher than the surface of the water and the ramp is inclined at an angle of 26.5 ∘ above the horizontal.
Part A If the seal reaches the water with a speed of 4.10 m/s, what is the work done by kinetic friction?
Part B What is the coefficient of kinetic friction between the seal and the ramp?

, b) 
![W_{fr} = (116\,kg)\cdot (9.807\,\frac{m}{s^{2}} )\cdot (1.85\,m-0\,m) + \frac{1}{2}\cdot (116\,kg)\cdot \left[(0\,\frac{m}{s} )^{2} - (4.10\,\frac{m}{s} )^{2}\right]](/tpl/images/0585/6467/6dd5e.png)
