Exercise 2.4.2: Consider a mass and spring system with a mass m 2, spring constant k 3, and damping constant c 1. a) Set up and find the general solution of the system. b) Is the system underdamped, overdamped or critically damped

into the screen

explanation:

the wind is hitting the car into the screen

f=ma newton's second law 7x8=56n

if the person is shown to have +90n, then ans is -10n.

if the person is shown to have -90n, then ans is +10n.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
