It was once recorded that a jaguar left skid marks that were 290 m in length. assuming that the jaguar skidded to a stop with a constant acceleration of -3.90 90 m/(s^ ^ 2) , determine the speed of the jaguar before it began to skid .

1/0.14nm = 10^10/1.4 a lot

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.

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.

not too sure thinking all accelerations are pointed down
