Question

josh rowed a boat 1 mile out into the lake then turned right and rowed another 1/2 mile. draw a vector diagram thats shows his resultant displacement. be sure to label all vectors

Answer 1

By rowing out of the lake, I will assume that the motion is up. So, the direction is north. Turning right, the direction now becomes east. The vector diagram would then be a straight arrow going up. On the head of this arrow, we draw another arrow going right. The length of the second arrow should be approximately half of the first arrow in order to do proper scaling. 

Answer 2

displacement = 1.12 miles

Step-by-step explanation:

As we know that it moves 1 miles straight and then turn 0.5 miles right

so here the net displacement can be shown as in the diagram because we know by the vector addition rule that when two vectors are joined head to tail then the resultant is always in the reverse order that is from tail to head.

So here the resultant is given by the hypotenuse of the given right angled triangle.

The resultant is given as

`d^2 = 1^2 + 0.5^2`

`d = √(1.25)`

`d = 1.12 miles`
