A mass of 12 kg is resting on a horizontal surface without friction. A force of 107 Newtons is applied in the +x direction, a force of 13 Newtons is applied in the -x direction, and a force of 11 Newtons is applied in the -y direction (downward). What is the acceleration of the mass in m/s2? If in the -x direction, include a negative sign.
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...
1) A mass of 12 kg is at rest on a horizontal surface. One force of 33 N is applied at an angle of 32 degrees below the horizontal (in the +x direction), and a force of 14 N is applied vertically upward (perpendicular and away from the surface). What is the acceleration (in the x direction) of the mass in m/s2? If in the -x direction, include a negative sign.
3) A mass of 9 kg is at rest on a horizontal surface. One force of 40 N is applied at an angle of 18 degrees below the horizontal (in the +x direction), and a force of 9 N is applied vertically upward (perpendicular and away from the surface). If these forces are applied for 2.3 seconds, what is the velocity (in the x direction) of the mass in m/s? If in the -x direction, include a negative sign.
6) A mass of 5 kg is at rest on a horizontal surface. One force is applied at an angle of 27 degrees below the horizontal (in the +x direction), and a force of 7 N is applied vertically upward (perpendicular and away from the surface). If after 3 seconds, it is moving at 10 m/s in the +x direction, what is the amount of force that was applied below the horizontal in Newtons?
A mass of 4 kg is placed on a horizontal surface with a coefficient of kinetic friction of 0.29. A force is applied vertically downward to it and another force of 88 Newtons is applied at 11 degrees below the horizontal. As it moves 9 meters in the +x direction it loses 194 Joules of kinetic energy. What is the amount of the force which is applied downward in Newtons? * the answers is 316.17, but how do you get...
A mass of 8.0 kg lies at rest on a horizontal surface with a coefficient of kinetic friction of 0.60 and a coefficient of static friction of 1.50. Then, a force of 20 Newtons is applied in the +x direction, a force of 40 Newtons is applied in the -y direction, and another force is applied in the +y direction. For the unknown force in the +y direction, what is the minimum force it needs to be such that the...
An object with a mass of 5 kg lies is on a horizontal surface with a coefficient of kinetic friction of 0.75. A force of 30 Nis applied to it DOWNWARDS, perpendicular to the surface, a force of 40 N is applied to it at an angle of 30 degrees above the +x axis, and a force of 20 N is applied to it in the negative x direction. The mass moves 10 m in the positive x direction with...
4) A mass of 3 kg has a force of 73 Newtons applied to it in the +x direction on a horizontal surface with friction. It has overcome static friction and moves 4 meters over the surface with friction. As it moves over the surface, its speed changes from 9 m/s to 12 m/s. What is the amount of friction acting on the mass in Newtons?
A mass of 7 kg is resting on a horizontal, frictionless surface. Force 1 is applied to it at 23 degrees below the horizontal, force 2 has a magnitude of 19 N and is applied vertically downward, force 3 has a magnitude of 3 N and is applied vertically upwards, and force 4 has a magnitude of 21 N and is applied in the-x direction to the object. When these forces are applied to the object, the object moves 9...
