Refer to the following information for the next two questions.
True or False:
This freebody diagram would only apply to an object resting on a supporting surface.
True
False
If the mass of this object equals 5 kg, what is the magnitude of the normal force exerted on it by the supporting surface?
Refer to the following information for the next two questions.
True or False:
According to this freebody diagram, the object is accelerating to the right on a frictionless, supporting surface.
True
False
If this object weighs 49 N and the applied force equals 10 N, what is the magnitude of the resulting acceleration?
Refer to the following information for the next two questions.
True or False:
According to this freebody diagram, the object is moving at a constant velocity, towards the left, across a supporting surface in the presence of friction.
True
False
If this object weighs 49 N and the applied force equals 10 N, what is the magnitude of the frictional force present between the object and the supporting surface?
Refer to the following information for the next two questions.
Which choice is correct? This object would be
losing speed
gaining speed
moving at a constant velocity
at rest
The object weighs 49 N and the frictional force between it and the supporting surface equals 10 N. If the applied force is reduced to 6 N, what is the magnitude of the resulting acceleration?
Refer to the following information for the next two questions.
Which choice is correct? This object is
moving to the left and gaining speed.
moving to the left and losing speed.
moving to the right and gaining speed.
moving to the right and losing speed.
The object weighs 49 N and the frictional force between it and the supporting surface equals 10 N. If the applied force is removed, what is the magnitude of the resulting acceleration?
Refer to the following information for the next two questions.
Which choice is correct? This object is
moving to the right and losing speed.
moving to the right and gaining speed.
moving to the left and losing speed.
moving to the left and gaining speed.
A second object weighing 29.4 N replaces the original 5 kg mass. As a direct consequence of the reduced mass, the retarding frictional force is now 6 N. Once again a horizontal force equaling 10 N is applied. What is the magnitude of the resulting acceleration?
Refer to the following information for the next two questions.
True or False:
This freebody diagram would only apply to an object being raised vertically at a constant velocity.
True
False
