18. a boat is moving across a lake during a rate of 67 m/s. how long does it take the boat to travel 550 m?
check answer and example problem below. fill in all s guess steps to get credit.
givens:
unknown:
equation:
substitute
solve:

1)    Givens:         time - 1 hr 23 min

     Unknown:     displacement, velocity

     Equation:      d = v x t

      Substitute:     -

      Solve:            -

2)  Givens:          velocity - 67 m/s; distance - 550 m

    Unknown:    time

    Equation:     t = d/v  s

    Substitute:   t = 550/67  s

    Solve:          t = 8.21 s

Explanation:

The relation between the velocity, displacement, and time is given by the equation,

                                           velocity = displacement / time

Or, displacement of a body is equal to the product of its velocity and time taken to travel the distance.

If there are two knowns in the equation, the unknown can be calculated from the above relation.

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.
