In Example 6-6 (Connected Blocks), suppose m1 and m2 are both increased by a factor of 2. (a) Does the acceleration of the blocks increase, decrease, or stay the same? (b) Does the tension in the string increase, decrease, or stay the same?

Solution 42P

Step 1 of 3</p>

We are required to compare the acceleration of the system and tension in the string when each mass is increased by two times from previous values.

Step 2 of 3</p>

Part a

From the example 6-6,

The acceleration of the blocks,

The new masses,

Therefore, the new acceleration is,

Therefore, the new value of acceleration stays the same as the previous value.
