What length of rope must the operator pull and what is the ideal mechanical advantage (MA) of the pulley system if the 15 N load is to be raised 1 m? (Assume the rope is sufficiently long to accommodate movement of the load and that all pulleys are frictionless.) A 1.0 m, MA=3 B 3.0 m, MA=3 C 1.0 m, MA=1/3 D 3.0 m, MA=1/3

correct it is c.) b b

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
