An object accelerates uniformly from rest. If the final velocity of the object after 6.0 s is 18 m/s east, how far did the object travel?

54m

Explanation:

Given parameters:

Initial velocity  = 0m/s

Time taken  = 6s

Final velocity  = 18m/s east

Unknow:

How far did the object travel  = ?

Solution:

To solve this problem, we use one of the kinematics equation:

 We first find the acceleration which is the change in velocity

So;

        S  =    

    S is the distance  

    v is the final velocity

    u is the initial velocity

    t is the time taken

  Therefore;

       S =  x 6  = 54m

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.

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
