A man standing on ground throws a piece of gum upwards at a velocity of 12.6 m/s. After 1.7 seconds in the air, the gum sticks onto a tree branch above him. After being stuck on the branch for 4.8 seconds, the gum falls back down to the ground. Calculate, a) the height of the tree branch above the man’s head, and b) the total time it took from when the piece of gum was thrown to when it landed on the ground.
a) y = 6.97 m
b) t = 7.681 sec
