A football game customarily begins with a coin toss to determine who kicks off. The referee tosses the coin up with an initial speed of 6.00 m/s. In the absence of air resistance, how high does the coin go above its point of release and what is the total time the coin is in the air before returning to its release point? (1.84 m; 1.22s) Standing on a bridge, you throw a stone straight upward. The stone hits a stream, 44.1 m below the point at which you release it, 4.00 s later. (a) What is the velocity of the stone just after it leases your hand? (b) What is the velocity of the stone just before it hits the water? (8.60 m/s; -30.6 m/s)
