Question 1.
What is the resultant velocity if two objects move at 10 m/s east?
Show hintHide hint
Remember to add the velocities since they are in the same direction.
Question 2.
Calculate the resultant of 15 m/s north and 15 m/s east.
Show hintHide hint
Use the Pythagorean theorem for perpendicular velocities.
3Question 3.
What is the formula for calculating resultant velocity when two velocities act in the same direction?
- v_R = v_1 + v_2
- v_R = v_1 - v_2
- v_R = v_1 * v_2
Show hintHide hint
Think about what happens when velocities align.
4Question 4.
For perpendicular velocities, which theorem is used to find the resultant?
- True
- False
Show hintHide hint
Recall the relationship between the sides of a right triangle.
Question 5.
A car travels 25 m/s northeast and another 35 m/s northwest. Find the resultant velocity and its direction.
Show hintHide hint
Use vector components and then apply the Pythagorean theorem.
Question 6.
A person walks 30 m north and then 40 m east. Calculate their resultant displacement and direction.
Show hintHide hint
Think of the path as a right triangle.
