An object starts at 4m/s and accelerates to 6m/s in 10 seconds. Find its displacement. (the answer is 50 m but I don't know how to solve the question)

Explanation:

The 2 equations we need here are, first:

and then once we solve for the acceleration here:

Δx

Solving for acceleration:

and now we will use that in the other equation:

Δx and

36 = 16 + Δx and

20 = Δx and

Δx so

Δx = 50 m

their crystal patterns have been disrupted by stress

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
