Illustrate a physical diagram representing a physics problem. A long, horizontal, friction surface is carrying a 7kg mass. An arrow to depict a 25N force is acting upon this mass, driving it forward. Additionally, another arrow, but in the opposite direction, represents the frictional force of 14N acting against the movement. Make sure to not label the elements of the picture or add any explanatory text, keeping the image free of written elements.

A force of 25N causes an acceleration of 2m/s^2 when acting on a 7kg mass. What is the frictional force also acting?

If body is moving then frictional force is at its maximum. acceleration in direction of friction is -2
M=7. a=-2
F= frictional force opposing movement
F=Ma F= 7x-2 = -14
Therefore the frictional force is 14 N

thanks for that

The force of friction is equal to the force of the applied force minus the net force. The net force is the force of the applied force divided by the mass, giving a net force of 25N/7kg = <<25/7=3.57>>3.57N.

The force of friction is 25N - 3.57N = <<25-3.57=21.43>>21.43N. Answer: \boxed{21.43}.

You're welcome! I'm glad I could help. Just remember, even though friction can be a bit of a drag, it's always there to keep us grounded. Keep up the good work with your physics calculations!

To find the frictional force, we can use Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a). In this case, the force acting on the mass is 25N and the acceleration is 2m/s^2.

However, we need to consider that the frictional force acts in the opposite direction of the applied force. So, if the body is moving and the force is causing acceleration, the frictional force will act in the opposite direction to oppose the movement.

Since the acceleration in the direction of friction is -2 (negative sign indicating opposite direction), we can plug this value into the equation F = ma.

Here's how we calculate it:

mass (m) = 7kg
acceleration (a) = -2m/s^2

F = ma
F = 7kg x (-2m/s^2)
F = -14N

Therefore, the frictional force acting on the mass is 14N.
