Avehicle moves in a straight line with an acceleration of 4 km/h2. by how much does the speed change each second? answer in units of km/h.

The speed of the vehicle changes in each second is, v = 0.00111 Km/h

Explanation:

Given,

The acceleration of the vehicle, a = 4 Km/h²

Converting it into m/s,

                                                    a = 0.0003086 m/s²

In each second the vehicle covers 0.0003086 m

The speed of the vehicle in each second is given by 0.0003086 m/s

Converting it into Km/h

                                     v = 0.00111 Km/h

Therefore, the speed of the vehicle changes in each second is, v = 0.00111 Km/h

the answer is false

explanation:

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.
