If an object moved at 30.0 m/s and at a later time covers half the distance in the same time, calculate its new speed.

Joe moved to a new town and was having a hard time making friends. Recently he met some people he really liked at a party. They started smoking marijuana and offered him some. He smoked the marijuana, even though he didn't want to.

If a ball is given a push so that it has an initial velocity of 5 m/s down a certain inclined plane, then the distance it has rolled after t seconds is given by the following equation. s (t) = 5t + 2t2 (a) Find the velocity after 2 seconds.
