yes i should've mentioned that The coefficient only applies to the right block. Well i know how to do find T if i find a first. But i was wondering if there was a way to find T before finding a.

Homework Statement Homework Equations refer to 1. The Attempt at a Solution The answer is 9.1 I've done everything from adding the two equations, to plugging in values I am completely stuck. I can find the tension if i solve for acceleration first. But without knowing the...

Yes i know how to add vectors... I'm pretty sure i wouldn't get a question like this for homework if i didnt

I'm having trouble understanding the addition part Firstly you came up with 50 by doing the Ftotal=mass x acceleration I am assuming right? Resultant x would then yes be 50cos15 but the force of the first dude is 100N[N25*W] how are you to know to assume to use SIN ? terrible but rough drawing

I meant why are you using the SIN function, i was taught that you always use cos if you are doing X component and always use Sin for Y component, so i know why you used that force, But why Sin function?

why are you using 100"Sin"25 if its the x coordinate you are looking for? because you are adding them

What was your method? what did you do?

No, Thats the resultant force of the two. I'm asked to find the force exerted on the ball by the second player so its going to look something like 100N [N25*W]= Force of first soccer player 104N[S3.3*W] is the second players exerted force on the ball somehow (I checked the back of my textbook)...

I have Ftotal by using a= (fx-Ff)/m but the answer in my textbook says its 104N [S3.3*W] I have no idea how they got there. Because Ftotal is 50N based on the equation a= (fx-Ff)/m I'm aware that the Mass times the Acceleration gives you to total force but I'm getting no where near 104

so are you saying my expression should be Fn= -mg+Fsin45 ?

Homework Statement A gardener pushes down on the handle of a lawnmover, applying a force of 250N. The handle is inclined at an angle 45* to the horizontal. If the coefficient of the kinetic friction between the wheels of the lawnmower and the ground is 0.40, what is the acceleration of the...

Homework Statement Two players kick a soccer ball at the same time. If one player applies a force of 100N[N25*W] and the 250g ball experiences an acceleration of 200m/s^2 [W15*S], determine the magnitude and direction of the force applied by the second player.Homework Equations Fnety=F1y+F2y...
