A monkey throws a banana Eastward from the top of a tree 40m above the ground, at a 30degree upward angle and with an initial speed of 15 m/s. Gravity acts on the banana at g = 10m/s^2 and a wind from the North accelerates the banana at 6 m/s^2. If the base of the tree is the origin and North is in the positive y direction, -Find a formula for the position of the banana after t seconds. -How many seconds will pass before the banana is again level with the top of the tree?
