A monkey, hanging on a tree, is at a height of 3m from the ground. Ronaldo sees it from a distance of 6m. He kicks a ball towards the monkey with an initial speed of vo m/s and with an angle 0 = 30° from the horizontal. (a) Taking unit vectors i and j as horizontal and vertical unit vectors, respectively: Find the initial velocity vo such that the ball can reach the monkey (note: the money does not move). (b) Find the time t, when the monkey can catch the ball. (c) When the monkey catches the ball, has the ball already passed the highest point on its trajectory? Show your working.

In an attempt to escape a desert island, a castaway builds a raft and sets out to sea. The wind shifts a great deal during the day, and she is blown along the following straight lines: 2.50 km and 45.0 north of west, then 4.70 km and 60.0 south of east, then 130 km and 25.0 of west, then 5.10 km due east, then 1.70 km and 5.00 east of north, then 7.20 km and 55.0 south of west, and finally 2.80 km and 10.0 north of east. Use the analytical method to find the resultant vector of all her displacement vectors. What is its magnitude and direction?
