a 107 - kg skater with an initial speed of v=55 m/s coasts up a H=13-m-high rise as shown in the figure. The slope angle is theta=55. what is her final speed at the top? Assume the coefficient of friction between her skateboard and the ground is .185 (hint: find the distance traveled up the incline assuming a straight-line path as shown in the figure.) Use g=10 m/s^2
