Answer:

let the coefficient of friction be ß

Step-by-step explanation:


from \: third \: law \: of \: solid \: friction \\ friction = \beta * R \\ where \: R \: is \: the \: normal \: reaction \\ 46 = 0.30 * R \\ R = (46)/(0.30) \\ R = 153.33 \: N \\ but \: R = mg \\ where \: mg \: is \: the \: weight \\ hence \\ weight, W = 153.33 \: N
