Question

8. Suppose that two carts, one twice as massive as the other, fly apart when the compressed spring that joins them is released, as shown below. Upon explaining your reasoning, what is the acceleration of the heavier cart compared to that of the lighter cart as they start to move apart? [2] mwand 2m o o 9. A total of two 20-N forces and a 40-N force act on the hanging flower pot, as shown below. Will the plant experience an acceleration? Provide an explanation in support of your answer. [2] 20 N 20 N 40 N

Answer 1

(According to guideline 1 question is answered)

8.The spring apply equal forces to both masses

$m_{1}a_{1}=m_{2}a_{2}$

also

m₂=2m₁

$m_{1}a_{1}=2m_{1}a_{2}$

$a_{2}=\frac{a_{1}}{2}$

so the acceleration of bigger body is half of smaller one.
