Aparticle undergoes two displacements. the first has a magnitude of 11 m and makes an angle of 82 ◦ with the positive x axis. the result after the second displacement is 8.7 m directed at an angle of 135◦ to the positive x axis using counterclockwise as the positive angular direction schoenzeit (ms83473) – assignment 01-1 – pusch – (19512020) 5 135◦ 82◦ 11 m 8.7 m find the angle of the second displacement measured counterclockwise from the positive x axis (i. e., a positive angle). answer in units of ◦ .

Explanation:

First displacement of the particle is given as

= 11 m at 82 degree with positive X axis

so we can say

resultant displacement of the particle after second displacement is given as

r = 8.7 m at 135 degree with positive X axis

so we can say

now we know that

now we have

so we will have

so angle of the second displacement is given as

wavelength divides in half and speed stays the same.

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
