QUESTION:
Ant on a page An ant is walking due east at a constant speed of 2 hr on a sheet of paper that rests on a table. Suddenly the sheet of paper starts moving southeast at \(\sqrt{2} \mathrm{mi} / \mathrm{hr}\). Describe the motion of the ant relative to the table.
ANSWER:Solution 70E
Step 1 of 1 :
In this problem we need to describe the motion of the ant relative to the table when the sheet of paper starts moving southeast at mi/ hr.
Given that an ant is walking due east at a constant speed of 2 mi/hr on a sheet of paper that rests on a table.
The magnitude of the motion of the ant relative to the table is ;
, since from cosine rule.
= , since cos(.
