ound, that had a coefficient of kinetic friction mu_k = 0.645. I applied a tension force FR=4763.7N to my pet cow using the rope. Brisket moved up the ramp with an acceleration of magnitude 4.70m/s2. With this information, including friction on the ramp, what is Brisket's mass (in kg)?
Hint: Tackle this by first identifying all the forces involved and then drawing Brisket's free-body diagram. After that, resolve all the forces into their components, including relating kinetic friction to the normal force. (I suggest you define your coordinate system so that the x-axis is parallel to the ramp and the y-axis is perpendicular to the ramp.) Note which groups of forces balance and which don't (and thus produce the components of a net force). Finally, use Fnet = ma to solve for Brisket's mass.
I'd really appreciate if someone could help me with this problem. I've spent a lot of time trying to figure it out with no avail. Thank you very much.

F=4.70m/s2*9.8 = 117.9085
errors galore interior the Aussie remark field! i'm afraid i visit might desire to contradict you on a minute assertion you made that Dilshan by no ability gets out on an identical time as taking part in the Dilscoop! I relatively endure in suggestions the adventure because it became into against India and that i can declare with coverage that (so a ways as I endure in suggestions), he became into caught at short effective leg attempting to emulate the Dilscoop! Coming on your Q, it relatively surprises me to comprehend that the commentators from Australia lack the certainty of a globally properly-cherished shot! It in basic terms ought to have been a case of lack of information (it wont be incorrect to declare yet Aussies, someplace down the line indulge interior the adage - lack of information is bliss) there have been different experts too who're sturdy exponents of this shot! H. Gibbs, AB De Villiers emulate it rather properly! AB does not bypass with the entire bat backwards yet nevertheless it remotely resembles the Dilscoop! there have been rather an excellent variety of names linked with this shot! Dilscoop, Palluscoop (a brainchild of the IPL), scoop shot, dil hook (lol) and now ramp shot are all different names for an identical shot! Aussie commentators are going bonkers! by no ability heard them forget approximately the 'larger shrink' or the 'opposite sweep' or the 'change hit' or the 'helicopter shot'! it quite is strange and disgraceful to some volume! BQ -> larger sweep? Howz that? Cheers! :)
