A square, four-legged table with a weight of 400 N rests on an even concrete floor. Assuming the weight is evenly distributed, what is the direction and magnitude of the normal force between the floor and each foot of the table?
|
The floor provides a normal force vertically upward (perpendicular to the floor) on each leg with a magnitude of 100 N. |
|
The floor provides a normal force parallel to the floor on each leg with a magnitude of 100 N. |
|
The floor provides a force vertically upward (perpendicular to the floor) on each leg with a magnitude of 400 N. |
|
The floor provides a force parallel to the floor on each leg with a magnitude of 400 N. |

A trunk with a weight of 200 N rests on the floor. The coefficient of static friction between the trunk and the floor is 0.50, and the coefficient of kinetic friction is 0.26. (a) What is the magnitude of the minimum horizontal force with which a person must push on the trunk to start it moving? (b) Once the trunk is moving, what magnitude of horizontal force must the person apply to keep it moving with constant velocity? (c) If...

One end of a meter stick is pinned to a table, so the stick can rotate freely in a plane parallel to the tabletop. Two forces, both parallel to the tabletop, are applied to the stick in such a way that the net torque is zero. The first force has a magnitude of 2.00 N and is applied perpendicular to the length of the stick at the free end. The second force has a magnitude of 6.00 N and acts...
