A rocket, R, rises vertically from a point A on level ground. It is observed from another point B on the ground where B is 10 km from A. When the angle of elevation has the value radians, this angle is increasing at the rate of 0.005 radians per second. Find, 4 in m s', the velocity of the rocket at that instant. [100 m s']

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?
