Answer:
Is safe to use the bag.
Step-by-step explanation:
To solve this problem we must use Newton's second law which tells us that the resulting force is equal to the product of mass by acceleration.
F = m*a
where:
F = force [N] (units of Newtons)
m = mass = 15 [kg]
a = acceleration = 7 [m/s²]
Now replacing these values in the previous equation:
F = 15*7
F = 105 [N]
F < 230 [N]
The force of 105 [N] is lesser than the maximum resistance force, therefore is safe to use the bag.
