Example 12.1
The car moves in a straight line such that for a short
time its velocity is defined by v = (0.9t2 + 0.6t) m/s
where t is in sec. Determine it position and acceleration
when t = 3s. When t

When the skier reaches the point A along the parabolic
path, he has a speed of 6m/s which is increasing at
2m/s2. Determine the direction of his velocity and the
direction and magnitude
