Problem: A football coach sits on a sled while two of his players build their strength by dragging the sled across the field with ropes. The friction force on the sled is 1200Nand the angle between the two ropes is 25o.

Part A: How hard must each player pull to drag the coach at a steady 2.50 m/s? Assume both players pull with the same force.

Rework your solution from the beginning and check each step carefully.
