Acar traveling at 15 m/s passes a police car. at that instant, the police car accelerates at a constant rate of 3 m/s^6 in pursuit. we wish to find how much time elapses before the officer catches the car. a. choose a coordinate system for this problem and identify the initial states starting when the car passes the police. b. define the final state or conditions which enables you to answer the above question. c. to solve this problem identify the two equations (one for each vehicle) which satisfy part b. solve for the unknown time.

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.

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).
