Here are 10 physics questions about vectors for you to solve: 1. A car is traveling at 60 km/h towards the west. If the car turns 30 degrees towards the north, what is the resulting velocity of the car? 2. Two forces of 5 N and 8 N act on an object in the same direction. What is the net force on the object? 3. An airplane is flying east with a velocity of 300 m/s. If it encounters a crosswind blowing north at 50 m/s, what is the resultant velocity of the airplane? 4. A ball is thrown with a velocity of 20 m/s at an angle of 30 degrees above the horizontal. What is the horizontal component of its velocity? 5. A boat is moving across a river with a velocity of 5 m/s to the north. If the river current is flowing at 2 m/s to the east, what is the resultant velocity of the boat? 6. An object undergoing projectile motion has an initial horizontal velocity of 10 m/s and an initial vertical velocity of 15 m/s. What is the total velocity of the object? 7. A force of 20 N is applied at an angle of 30 degrees to the horizontal. What are the horizontal and vertical components of this force? 8. A car is moving at a speed of 40 km/h to the south. If it accelerates at a rate of 4 m/s^2 to the east for 10 seconds, what is its final velocity? 9. A person walks 10 meters east, then turns and walks 6 meters to the north. What is the magnitude and direction of the person's displacement? 10. A rocket is launched with an acceleration of 20 m/s^2 to the east. If the net force on the rocket is 5000 N, what is the mass of the rocket?

English short note about Apostrophe('). Apostrophes are primarily used in two ways: to indicate possession and to create contractions. Here are some examples of using apostrophes to indicate possession: 1. The cat's tail is fluffy. (The tail belongs to the cat.) 2. My parents' house is beautiful. (The house belongs to my parents.) 3. The book's pages are torn. (The pages belong to the book.) And here are some examples of using apostrophes to create contractions: 1. I can't go to the party. (can't = cannot) 2. We won't be late. (won't = will not) 3. That wasn't the right answer. (wasn't = was not) Remember, an apostrophe is not used to make a word plural. For example, instead of "apple's" (to indicate more than one apple), you would simply write "apples."
