Homework Statement
Two linebackers simultaneously hit a quarterback, who has a mass of 90 kg. One linebacker exerts a force on the quarterback of 500 N, 25° N of E. The other linebacker exerts a force on the quarterback of 450 N, 60° S of E. Determine the net force acting on the quarterback and the quarterback’s acceleration.
I have to draw a force diagram that represents this question as well..
Given:
m= 90kg
Applied force linebacker 1 on quarterback (FaL1Q)= 500N
Applied force linebacker 2 on quarterback (FaL2Q)= 450N
Fg= -882.9N
Homework Equations
F= ma
Trigonometric functions (cosine and sine)
The Attempt at a Solution
I have no idea how to draw a force diagram of this question but I think I managed to find a solution although I don't know if it's right..
Using sine and cosine ratios,
Fax= 453.2N, Fay=211.3N
Fbx=225N, Fby=389.7N
Therefore, Fnet in the x is +678.2N (453.2N+225N)
and acceleration is +7.54m/s/s (687.2N/90kg)
Is this solution correct? Is this question asking for me to get net force in the x or y? Do both answers actually have positive signs to them?
*************COULD YOU PLEASE TELL ME HOW TO DRAW A FORCE DIAGRAM OF THIS?*********
Thank you in advance!
