A car is driven 225 km west and then 98 km southwest (45º). What is the displacement of the car from the point of origin (magnitude and direction)? Draw a diagram.
Solution:
Explanation:
Given:
Initial magnitude of car’s displacement is 225 km in west direction. Then the car turns
Formula used:
The magnitude of the resultant vector and direction can be obtained using the following formulae:
Where, P and Q are vectors and
Calculations:
As per question:
Substitute the values and solve to find the magnitude of the resultant displacement.
Now, substitute the values to find the direction:
It will be directed South of West.
It can be represented as follows:
