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?

Having a lot of trouble with this one

If X= -2, Y= 5, and Z = -1 Evaluate the expression

X(Y squared - 2Z) -8 divided by Z(Y - X squared)

If X= -2, Y= 5, and Z = -1 Evaluate the expression

X(Y squared - 2Z) -8 divided by Z(Y - X squared)
