Question: Consider a rower in a scull as in Figure P8.46. The oars arent accelerating, and they are rotating at a constant speed, so the net

Consider a rower in a scull as in Figure P8.46. The oars aren’t accelerating, and they are rotating at a constant speed, so the net force and net torque on the oars are zero. An oar is 2.8 m long, and the rower pulls with a 250 N force on the handle, which is 0.92 m from the pivot.

FIGURE P8.46

a. Assume that the oar touches the water at its very end. What is the drag force from the water on the oar? Assume that the oar is perpendicular to the boat, and that the force of the rower and the drag force are both perpendicular to the oar.

b. Given that both oars are the same, what is the total force propelling the boat forward?
