Question

What is the net force needed to lift a full grocery sack (weighing 210 N) uniformly? What is the net force

Answer 1

The net force needed to lift a full grocery sack uniformly is 32.115 N.

What is Net force?

When two or more forces are acting on the system of objects, then the to attain equilibrium, net force must be zero.

Given the weight of sack W = 210N and the acceleration a = 1.5m/s².

The mass of the sack will be

m = Weight / acceleration due to gravity

m = 210 N/9.81 m/s²

m = 21.41 kg

Using Newton's second law, the net force will be

F = mass x acceleration

F= 21.41 x 1.5

F = 32.115 N

Thus, the net force is 32.115 N.
