A car starts to move from rest and covers a distance of 360m in one minute. Calculate the acceleration of the car.

Explanation:

When the car moves , the distance covered is calculated by the relation

S = u t + a t²

In this question u = 0 , because car was at rest initially

Thus S =   a t²

here S is displacement and a is the acceleration of car

Therefore  360 =   a ( 60 )²

Because time taken is one minute or 60 seconds

Therefore a =

or a = 0.2 m s⁻²

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.
