friend has given a special gift, a box of mass 10.0 Kg with a mystery surprise inside. The box is resting on the smooth (frictionless) horizontal surface of a table. a-)determine the weight of the box and the normal force exerted on it by the table. b-)now your friend pushes down on the box with a force of 40.0N, determine the normal force. c-)If your friend pulls upward on the box with a force of 40.0N, what now is the normal force?
A friend has given a special gift, a box of mass 10.0 Kg with a mystery surprise inside. The box is resting on the smooth (frictionless) horizontal surface of a table.
a-)determine the weight of the box and the normal force exerted on it by the table.
b-)now your friend pushes down on the box with a force of 40.0N, determine the normal force.
c-)If your friend pulls upward on the box with a force of 40.0N, what now is the normal force?
In determining the forces, consider all forces acting in the given direction and apply the equilibrium condition
a)
The weight of the box,
And is acting downward. And the normal force exerted by the table on the box is acting upward. And the box is at rest.
