A person pulls on a container on a horizontal frictionless surface with a force of 110 N in a direction of 40° above the horizontal. If the normal force on the container is 230 N, what is the mass of the container?
Homework Answers
We can resolve the force applied by person into two components.
Fx = 110 cos 40 = 84.26 N
Fy = 110 sin 40 = 70.7 N
Therefore, total normal force is
N = 70.7 + 230 = 300.7 N
we know
N = mg
m = N / g
m = 300.7 / 9.8
m = 30.68 Kg

3) A mass of 5 kg is resting on a horizontal, frictionless surface. Force 1 is applied to it at 20 degrees below the horizontal in the -x direction, force 2 has a magnitude of 88 N and is applied in the +x direction , and force 3 has a magnitude of 25 N and is applied vertically downwards. When these forces are applied, the normal force acting on the mass is twice the amount of its weight. Also, when...
