1. A top-fuel dragster starts from rest and has a constant acceleration of 40.0 m/s. What are the (a) final velocities and (b) displacements of the dragster at the end of 2.0 s and at the end of twice this time, or 4.0 s? 2. A jet is taking off from the deck of an aircraft carrier. Starting from rest, the jet is catapulted with a constant acceleration of 31 m/s along a straight line and reaches a velocity of 62 m/s. Find the displacement of the jet.
