Question

Erica and Tory are out fishing on the lake on a hot summer day when theyboth decide to go for a swim. Erica dives off the front of the boat with a forceof 45 N, while Tory dives off the back with a force of 60. N. a) Draw a vectordiagram of the situation. b) Find the resultant force on the boat.

Answer 1

a)

The diagram of the situation is shown below:

b)

Assuming the positive direction is to the right and from the diagram we have that the resultant force is:

$\begin{gathered} F=45-60 \\ F=-15 \end{gathered}$

Therefore, the resultant force is -15 N
