Abox is sliding across the floor from left to right. which diagram correctly shows the force of fiction acting on the box?

Friction in this case will act counter to the direction of the box's movement. The box moves left to right, so the force of friction acts in the opposite direction. (D)

Hello there!

first, we have two notions of the force of friction:

The force of friction is in the opposite direction of the motion direction.

It acts in the contact point between the objects.

Then if the box is moving from left to right, the friction force should point from right to left, and be in the bottom of the box (the contact point between the box and the floor).

The diagram that shows this is the D.

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
