A mass of 9 kg rests on a floor with a coefficient of static friction of 1.25 and coefficient of kinetic friction of kinetic friction of 0.1. One force is applied vertically downward of 10 Newtons and another force is applied at an angle of 15 degrees below the horizontal. Calculate what the magnitude this force needs to be in order to begin to move the mass. If the same amount of force is applied at the same angle above the horizontal, how far does the mass move horizontally in 3 seconds? Answer in meters. please show your work so i understand

A mass of 7 kg rests on a floor with friction. One force is applied vertically downward of 23 Newtons and another force is applied in the +x direction such that it just begins to move the mass. The force of 23 Newtons is then applied vertically upwards instead of downwards and another force is applied in the +x direction which just begins to move the mass that force is 141 Newtons less than the first case. What is the...

QUESTION 5 A mass of 12 kg is placed on a horizontal surface with friction with a coefficient of static friction of 0.81 and coefficient of kinetic friction of 0.44. A force of 13 Newtons is applied in the -y direction and a force of 16 Newtons is also applied in the -y direction. Another force is applied in the +x direction (see sketch). The force applied in the +x direction is increased until it is 1.9 times the force...
