Astudent moved up north along vector v1 and north east along vector v2 as shown in the diagram. if the magnitude of v1 is 7, x=4, and y=3 determine the magnutude of v2, the magnitude of r and the direction of r

x = 4

y = 3

From the diagram, it is clear that the x and y are the component of the vector. Since, x and y are perpendicular.

Hence,

Now, and x are in the same direction. Hence, we can add the magnitude.

= 7 + 4

y and are perpendicular and they are the components of R

Hence, the magnitude of R:

R = 11.4

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !

c. magnitude and direction
