Achild slides down a slide with a 28° incline, and at the bottom her speed is precisely one half what it would have been if the slide had been frictionless. calculate the coefficient of kinetic friction between the slide and the child. here's the two equations i used: sin28*m*g=m(v2/t) since v2=v1+at the other one is with friction: sin28*m*g-u*cos28*m*g=m((1/2*v2)/t)

(a) calculate the number of electrons in a small, electrically neutral silver pin that has a mass of 10.0 g. silver has 47 electrons per atom, and its molar mass is 107.87 g/mol. (b) imagine adding electrons to the pin until the negative charge has the very large value 1.00 mc. how many electrons are added for every 109 electrons already present
