A movie stuntman (mass 80.0kg) stands on a window ledge 5.0 mabove the floor. Grabbing a rope attached to a chandelier, heswings down to grapple with the movie's villian (mass 70.0 kg), whois standing directly under the chandelier.(assume that thestuntman's center of mass moves downward 5.0 m. He releasesthe rope just as he reaches the villian).
a) with what speed do the entwined foes start to slide acrossthe floor?
b) if the coefficient of kinetic friction of their bodies withthe floor is 0.250, how far do they slide?
the question is- Simplify the expression 4 • 3 + 4 • x.
it would help me a lot if you can get me the answer to this question before tomorrow 10:30am
I am a 13 year old in 7th grade that had a good grade in math (97) and it dropped to a 62 because I got confused with this stuff
please and thank you
