A grocery sack can withstand a maximum of 235 n before it rips. will a bag holding 18.5 kg of groceries that is lifted from the checkout counter at an acceleration of 5.0 m/s2 hold is 51.98N
Threshold force is 235N
Force or weight = mg
Where m = mass of object and g is the acceleration due to gravity
Mass of object it holds = 18.5kg
g = 9.81m/s^2
a = 7m/s^2
Because a is acceleration against gravity
Minimum force applied to lift the bag = (18.5 × (-7)) kgms^2
= -129.5N
Force of gravity, i.e its weight
= (18.5 × 9.81)N
= 181.48N
Net force acting on the bag from above =
(181.48 + (-129.5)) N
= 51.98N
Hence, An acceleration of 5.0 m/s2 hold is 51.98N
