JUST PART B PLEASE Part B

Blocks A and $B$ have a masses of $190kg$ and $250kg,$ respectively.$($Figure $2)$ The coefficient of static friction between A and $B$ and between $B$

and $C$ is $0\mathrm{.}200.$ The coefficient of static friction between the rope and peg $E$ is $0\mathrm{.}400.$ Pulley $D$ rotates freely, and $P=23\mathrm{.}0N.$ If $=60\mathrm{.}0$

degrees, what is the smallest magnitude, $T,$ of tension, $T,$ that causes block $B$ to move?

Express your answer numerically in kilonewtons to three significant figures.

Part C

Block A has a mass of $m_A=55\mathrm{.}0kg$ and rests on a flat surface. $($Figure $3)$The coefficient of static friction between the block and the surface

is ${}_A=0\mathrm{.}300.$ The coefficient of static friction between the rope and the fixed peg $B$ is $0\mathrm{.}290.$ The width of the block is $d=0\mathrm{.}230m.$ Find the

greatest mass, $m_C,$ that weight $C$ can have such that block A does not move.
