I need help with the attached problems, circled only, numbers 3 and 4. Could you please provide the answers and workings out to them. Please see attachment.
3. In example 6 - 6 (connected blocks), suppose m1 and m2 are both increased by a factor 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?
4. Suppose m1 and m2 in exmpale 6-7(Atwood's machine) are both increased by 1 kg. Does the acceleration of the blocks increase, decrease, or stay the same?
The solution is comprised of step-by-step explanations of how the acceleration and tension in the string change in the connected blocks when both block masses are increased.
