A ball is thrown upward with speed of 38.0m/s from top of building 240 m tall: a) How long will it take to reach ground? b)how long will it take for this ball to reach the highest point. c) How long after ball is thrown will it be found 265 m above ground? d) What is velocity of ball as it reaches the ground ? e) what will be the velocity of this ball at the highest point? f) how high above the ground will the ball ball be when it reaches the highest point? g) What is average speed of ball from time thrown until it strikes ground? Suppose that instead of throwing this ball upward it is thrown downward with a speed of 38.0m/s : h) How long will it take for ball to reach ground i) What is speed as it reaches the ground?
