Some dragonflies splash down onto the surface of a lake to clean themselves. After this dunking, the dragonflies gain altitude, and then spin rapidly at about to spray the water off their bodies. When the dragonflies do this "spin-dry," they tuck themselves into a "ball." If they spin with a linear speed of , and curl into a ball with a radius of , what is the centripetal acceleration they produce?
The tractor together with the empty tank has a total mass of . The tank is filled with of water. The water is discharged at a constant rate of with a constant velocity of , measured relative to the tractor. If the tractor starts from rest, and the rear wheels provide a resultant traction force of , determine the velocity and acceleration of the tractor at the instant the tank becomes empty.
