=Exam Question= Note - This question has a velocity that is NOT constant. Most Edexcel vectors questions have a concstant velocity. This example is to test your understanding. The velocity of a model boat, v ms –1, is given by: where t is the time in seconds and the vectors __**i**__ and **__j__** are east and north respectively.

Show that when t = 2.5 the boat is travelling south-east (i.e. on a bearing of 135°). Calculate its speed at this time. media type="custom" key="14217596"
