The figure shows that the wooden box is being pulled along a horizontal plane. what is the horizontal acceleration of the box to the left. provided that the coefficient of k. e on wood is 0.2. round your answer to the nearest 100th

dicrrdirrkdirckrrdrrk ; jhgfdsgrthyjkul; i'lkjhgfdskhjl; jhgdfs

which statement about this sum is true? −245+2.7

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

float.
