Question 7 2 pts A sled rider having a combined mass of 125 kg travels down the slope as shown in the figure. A friction force of 2 N acts between the slope and the sled. If he starts at rest on the top of the slope, calculate the speed (in m/s) of the sled rider when he reaches the bottom of the slope. [Enter the number up to one decimal place (Hint: Use conservation of total energy, use trigonometry to find the length of the slope, s and use it in Wother] 11 m 30
