Question

Consider the following figure. A horizontal table top is shown to extend righward from a vertical wall. An object of mass m1 hangs from a string that passes over a very light fixed pulley P1 anchored at the right edge of the table surface. The string connects to a second very light pulley P2. A second string passes around pulley P2 with one end attached to the wall and the other to an object of mass m2 on the frictionless, horizontal table. (a) If a1 and a2 are the accelerations of m1 and m2, respectively, what is the relation between these accelerations? (Use any variable or symbol stated above as necessary.) a2 = ?

To find the relation between the accelerations a1 and a2, we can start by analyzing the forces acting on each object.

For object m1 hanging from the string, there are two forces acting on it: the weight (mg1) pulling it downward and the tension in the string (T1) pulling it upward. Since the object is in equilibrium in the vertical direction, we can write:

mg1 - T1 = 0 ...(1)

For object m2 on the table, there are three forces acting on it: the weight (mg2) pulling it downward, the tension in the string (T2) pulling it to the left, and the normal force (N) acting upward. Since the object is also in equilibrium in the vertical direction, we can write:

N - mg2 - T2 = 0 ...(2)

Next, we can consider the horizontal forces acting on both objects. For object m1, the tension in the string (T1) is the only force acting on it horizontally, and it causes the object to accelerate to the right with acceleration a1. Therefore, we have:

T1 = m1 * a1 ...(3)

For object m2, the tension in the string (T2) is the only force acting on it horizontally, and it causes the object to accelerate to the left with acceleration a2. Therefore, we have:

T2 = m2 * a2 ...(4)

In addition to the tension forces, there is also friction acting on m2. However, since the table is assumed to be frictionless, we can ignore the friction force in this case.

Now, we can solve the system of equations (1), (2), (3), and (4) to find the relation between a1 and a2.

From equation (1), we have:

T1 = mg1

Substituting this into equation (3), we get:

mg1 = m1 * a1

Simplifying, we find:

a1 = g1 ...(5)

From equation (2), we have:

N = mg2 + T2

Substituting this and equation (4) into equation (2), we get:

mg2 + m2 * a2 = mg2 + T2

Simplifying, we find:

m2 * a2 = T2

Substituting equation (4) into this, we get:

m2 * a2 = m2 * a2

Since this equation is an identity, it means that a2 can have any value. Therefore, there is no direct relation between a1 and a2.

Answer: There is no direct relation between the accelerations a1 and a2.
