2. An object is thrown upward with a speed of 8 m/s from the roof of a building 10 m high. It rises and then falls back until it strikes the ground. (a) What is the greatest height above the ground that the object attains? (b) With what speed does the object strike the ground? (Notice that an object near the surface of the earth is subject to a gravitational force which produces a downward acceleration which may be assumed to be constant, of value g= 9.8m/s*) 5p+5pl
