(a) A missile is moving along a curved path, AB, from A towards B. At A the missile's velocity is 100 m/sec; its acceleration along the path depends on its distance, x, from A according to the relationship az = 200 – x, where x is measured along the path. What is the missile's velocity when it reaches B, which is x = 150m from A? If the radius of curvature of the path is 300 m at B, what is the missile's resultant acceleration at B?

200 x, where x is measured along the path.
at B?
(b)
A ship is moving relative to the water and you are given the following velocities:
Velocity
Magnitude Direction (degrees)
(kn/hour)
Absolute water velocity (tide)
Ship's velocity relative to water
120
20
90
The directions are measured clockwise from due north (i.e. due east is 90°). What is
the ship's absolute velocity (magnitude and direction)?
