one of your classmate has a friend with a boat. here is your classmate on water-skis being towed. in the absence of friction your classmate (m=62kg) would accelerate at 2.23m/s^2. a. determine the tension in the tow rope for there ideal conditions. (A FBD of the skier is expected) b. in the actual case friction with the water is the primary non-ideal condition. as a result of this your classmate reaches a top speed of 14.8m/s after 8.2s beginning from rest. what is the friction force of the water?
