A lady goes on a hike for $90 \text{ minutes}.$ Her average speed is $8 \text{ km/h},$ and she hikes in a direction that makes a $60^\circ$ angle with the eastward and a $30^\circ$ angle with the northward. Express her displacement using two direction components.

Assume that $\sqrt{3}$ is approximately $1.7.$

A car drives straight off the edge of a cliff that is 80 m high. At the scene of the accident you note that the point of impact is 160m from the base of the cliff. How fast was the car traveling in m/s when it went over the cliff?

Consider $g = 10 \text{ m/s}^2$
