Sheena pulls a sled along a snowy path on level ground with a maple syrup barrel, 26 kg, on the sled. The cord makes a 20 degree angle with the ground. Assume that the force of friction on the sled is determined by ? =0.16, even thought the surfaces are not dry.
Find a) The tension between the barrel and Sheena's hand.
b) The work done by Sheena while the sled moves 120m.
c) The work done by the ground on the sled while the sled moves 120m.
d) What is the total work done on the sled?
e) Find the normal force.
f) The work done by the normal force while the sled moves 120m.
