one resistance is 2 ohm the other one is 4 ohm. For parallel: R[tot]=V/I and (R[1]*R[2])/(R[1]+R[2]), therefore: V/I=(R[1]*R[2])/(R[1]+R[2]) For searies: R[tot]= V/I and R[1]+R[2], therefore V/I=R[1]+R[2] Now you have two unknown and two equations, isolate R[1] or R[2] from...

Homework Statement A solid sphere with mass "m" and radius "r", slides (without rotating) on a frictionless horizontal surface, with speed of V[0]. At time t[0] the sphere roll on a surface with friction "u", at time t[0] the ball is starts rotating as it glides aswell. At time t[1] the...
