Since the force of 10N was applied when the body was just about to move then the static or limiting frictional force F 10N The normal reaction R on the body is equal to its weight.

The friction force.
Friction is the force opposing the relative movement of strong surfaces liquid layers and material components sliding against one another. Rearranging the equation for F we find F fracmgmathrmDelta H-frac12mv2s The graph shown is the results take note of the red line ignore blue data where AAF is average applied force. You know that F ma so you can plug in the values to get Okay so the force applied to accelerate the car steadily is 5060 newtons.
