\fThe mass density of a bar of length 4 meters is given byp(.'L') : 3513 kg/m for 0 S .'L' g 4. The bar is cut into two pieces. Find that point (I along the bar such 6 that the cut pieces have the same mass. (HINT: Equate the integrals / 19(33) d3: 0 4 and / 33(33) d9\"; and solve for C.) C I::__::2_| C : 2 .f None of these
