A 40 kg football player leaps through the air to collide with and tackle a 50 kg player heading toward him also in the air. If the smaller player is moving at 9.0 m/s and the bigger player is moving at 2 m/s, what is the speed and direction of the tangled players?

the answer would be 32*f

this is poiselle's equation from fluid mechanic in physics. mech eng

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.
