Question

A)Determine the direction of the force F 2 (-300 N, -400 N). please show work if possible

B)Determine the direction of the force F 3 (-400 N, +300 N).

C)A string with one 10-g washer on the end is attached to the rearview mirror of a car. When the car leaves an intersection, the string makes an angle of 9 with the vertical.

What is the acceleration of the car? [Hint: Choose the washer as the system object for your force diagram. Use the vertical component equation of Newton's second law to find the magnitude of the force that the string exerts on the washer. Then continue with the horizontal component equation.]

Explanation / Answer

Here,

A) F2 = -300 N , -400 N

direction of F2 = 180 + arctan(400/300)

direction of F2 = 233.13 N

B)

(-400 N, 300 N)

direction of force F3 = 180 - arctan(300/400)

direction of force F3 = 143.1 degree

the direction of force F3 is 143.1 degree

c)

let the accleration of car is a

theta , a = 9 degree

acceleration = g * tan(9)

acceleration = 9.8 * tan(9)

acceleration = 1.55 m/s^2

the acceleration of the car is 1.55 m/s^2
