A vector force of F1 of 3N is due West , and a vector force of F2 of 8 N is directed in 40 degrees East of South. a. Draw each vector; calculate their components, and use the component method to determine the magnitude and the direction of the resultant vector F = F1 + F2 .

Suppose you walk 13.5 m in a direction exactly 15° south of west. You then walk24.5 m in a direction exactly 43° west of north.a. What is the x-component of the displacement in meters of your motion when you are walking south ofwest? Let east be the positive x directionb. What is the y-component of the displacement of your motion in meters when you are walking south ofwest? Let north be the positive y directionc. What is the x-component of the displacement of your motion in meters when you are walking west ofnorth? Let east be the positive x direction.d. What is the y-component of the displacement of your motion in meters when you are walking west ofnorth? Let north be the positive y direction.e. How far, in meters, are you from your starting point?

Part C: Density of Water             In this part, we will try to measure or calculate the density of water. As we have learnedin the lecture, the density of any matter will be the ratio of the mass of the given matterand the volume of the matter. We will have to obtain the data for the mass and the volumeof that given amount of water. We will use a rectangle container for this purpose. If we measurethe length, the width of the container, and if we pour the water in the container, we can calculatethe volume of the water. To get the mass of the water, we will measure the mass of the emptycontainer first, we will then measure the mass of the container with the water inside. The differenceof this two mass will be the net mass of the water that we are interested.          We will do three trials. We will just put different amount of water in the container. Different amount of water will give you different height, but the length and the width of the container is the same.         Since this…

The grid runs from -5 to 5 on both axes. Drawn on this grid are four vectors, labeled A⃗ A→ through D⃗ D→. This problem will ask you various questions about these vectors. All answers should be in decimal notation, unless otherwise specified. A. What is the xcomponent of A→? B.What is the y component of A⃗ ? C.What is the y component of B⃗ ? D.What is the x component of C⃗ ? E. In ordered pair notation, write down the components of vector B⃗  F. In ordered pair notation, write down the components of vector D G.What is true about B⃗  and D⃗ ? They have different components and are not the same vectors. They have the same components but are not the same vectors. They are the same vectors.

Stuck need help! The class I'm taking is physics for scientists and engineers! Problem is attached. please view attachment before answering.  Really struggling with this concept. Any help will be greatly appreciated! Please detail explain so I can fully understand how to solve.  Thank you so much.

QUESTION 2 Which of the following is an accurate statement? O A. It is possible to add a scalar quantity to a vector. O B. Even though two vectors have unequal magnitudes, it is possible that their vector sum is zero. OC. Rotating a vector about an axis passing through the tip of the vector does not change the vector. OD. The magnitude of a vector is independent of the coordinate system used. O E. The magnitude of a vector can be zero even though one of its components is not zero.

A  cannon is turned towards the west and a cannonball is fired. This cannonball has a velocity of 252 kmph at an angle 60 degrees. The cannonball lands on a hillside 100 metres above its starting level. What is the range of the cannon ball?  Make a simple sketch. Make a list of all given values, units, and the variables they represent. write the general form of the equation you are going to use. Insert the known values and solve. State at the start of the problem which direction is positive by using an up or down arrow. Keep the velocity components and time to 2 decimal places.
