Arabbit is traveling at a steady 6 m/s and (without knowing it) passes a wolf. the wolf takes off at the instant the rabbit passes it, accelerating at a steady rate of 2.0 m/s^2. how much time elapses before the wolf is moving as fast as the rabbit? how far is the wolf from the rabbit when it reaches this speed?

Engineers find a new metal that is stronger than steel but much lighter. this material is also significantly cheaper than what is currently used for most aircraft, available in large quantities, and easy to manufacture. the engineers are excited because this new material will lower the costs of buying and operating airplanes for companies. what is probably the best step for the engineers to make next?

Two steel balls, each of mass m, are welded to a light rod of length l and negligible mass and are initially at rest on a smooth horizontal surface. a horizontal force of magnitude f is suddenly applied to the rod as shown. determine (a) the instantaneous acceleration a of the mass center g and (b) the corresponding rate at which the angular velocity of the assembly about g is changing with time.
