Two masses are connected by a string. Mass mA rests on a frictionless inclined plane, while mB is initially held at a height of h above the floor. (a) If mB is allowed to fall, what will be the resulting acceleration of the masses? (b) If the masses were initially at rest, use the kinematic equations to find their velocity just before mass b hits the floor, (c) Use conservation of energy to find the velocity of the masses just before mB hits the floor. You should get the same answer as in part (b). EXPRESS YOUR ANSWER IN TERMS OF h, θ, g, mA, and mB.

Two masses are connected by a string. Mass $m_{A}$ rests on a frictionless inclined plane, while $m_{B}$ is initially held at a height of $h$ above the floor. (a) If $m_{B}$ is allowed to fall, what will be the resulting acceleration of the masses? (b) If the masses were initially at rest, use the kinematic equations to find their velocity just before mass $b$ hits the floor, (c) Use conservation of energy to find the velocity of the masses just before $m_{B}$ hits the floor. You should get the same answer as in part (b). EXPRESS YOUR ANSWER IN TERMS OF $h, θ, g, m_{A}$ , and $m_{B}$ .
