Your moving company is to load a crate of books on a truck with the of some planks that slope upward at the mass of the crate is 100 kg, and the coefficient of sliding friction between it and the planks is 0.500. you and your employees push horizontally with a combined net force once the crate has started to move, how large must f be in order to keep the crate moving at constant speed?

the force must be larger than F= 490N for example for a speed of 1m/s for 10s the force is 590N

Explanation:

The motion of the truck must be bigger than the Fk of friction that is opposite of the force both person are doing so:

Knowing the truck must be accelerated to get a constant speed the acceleration can be determinate by

It is at rest so

The force net of both person is

Asume for example that the speed they want is about 1 m/s for 10 s so the force have to be larger than 490N

jupiter

explanation:

it is so massive and has such a strong gravitational pull its likely prevented the formation of a planet between itself and mars in the asteroid belt

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.
