An object is thrown vertically upward with an initial speed of56.9 m/s. (Assume the object is thrown from ground level.)
(a) How high (in m) does it rise?
(b) How long (in s) does it take to reach this highestaltitude?
(c) How long (in s) does it take to hit the ground after itreaches the highest altitude?
(d) What is its speed (in m/s) when it returns to the level fromwhich it was initially released?
