# Find the resultant displacement of a bear searching for berries on the mountain. the bear heads 55.0º north of west for 15.0 m; then it turns and heads to the west for another 7.00 m. (use trigonometry to answer, but remember to draw a diagram to help your understanding.) give both the magnitude and the angle in your answer.

The acceleration of the car is 0.5 m/

Explanation:

In our case, the problem is about Motion in a Straight Line.

1. For the formula, we will use

where

is the final velocity, unit is in m/s

is the initial velocity, unit is in m/s

is the acceleration, unit is in m/

2. Let us list the given information, we have:

= 0 because the car starts from a stoplight

= 10 m/s

t = 20 s

a = ?

3. Now, we are ready to solve for the acceleration.

Using the formula, substitute the given information

Dividing both sides of the equation by , we have:

a = 0.5 m/

Therefore, the acceleration of the car is 0.5 m/.

Definition of acceleration

C, because its the only answer i know
You may find your answer with cosine rule after you have drawn the diagram. The answer should be 19.86m. The angle should be 16°46’.
