Question

The object in this diagram has a mass of 2 kg.

Answer 1

Answer:

$4 ms^{-2}$

Explanation:

Normal force - should be the reaction from the surface it's on - nullifies the weight of the object. At this point the only force is of $22-14 = 8N$ from whoever is pushing the square and the friction, towards the right. At this point we divide the force by the mass of the object to obtain an acceleration of $8/2 = 4 ms^{-2}$
