A horizontal force, F1 = 95 N, and a force, F2 = 18.9 N acting at an angle of θ to the horizontal, are applied to a block of mass m = 2.9 kg. The coefficient of kinetic friction between the block and the surface is μk = 0.2. The block is moving to the right. Calculate the normal force when the angle is 30. and acceleration when the angle is 30.

explanation: in any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called brownian motion). as a result, the particles have some kinetic energy (which is proportional to the temperature of the substance).

explanation:

have a great day!

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
