Pedro   who  is  on  top  of  a roof  of  a  high  building  drops  a  piece  of  metallic material.  A  second  piece of metallic material is  dropped    2.0   seconds  later.  How  far   apart  (k m) are  the  materials  when  the  second  material  has  reached  a  speed  of  15.0  m/s. Express  all answers  in  sig  figure  And  scientific notation.
A student throws a set of keys vertically upward to his fraternity brother, who is in a window a distance h above. The brother's outstretched hand catches the keys on their way up a time t later. (Answers should be in terms of h, g, and t. Let up be positive. Indicate the direction with the sign of your answer.) (a) With what initial velocity were the keys thrown? (b) What was the velocity of the keys just before they were caught?
Two friends are tossing balls from the main floor of the auditorium to the balcony. One person stands exactly 4.0 m above the other person, and both release and catch the balls at the same height above their feet. The balls are always caught on their way down. The boy on the main floor releases his ball with an initial velocity of 25 m/s [up]. With what velocity should the girl on the balcony throw her ball at the same moment, so that both balls will be caught by the other person at exactly the same time
