3. A force of 90N pushes downward at an angle of 32° to the horizontal on an object resting on the floor. The object does not move. If the Normal force acting upward is 200 N find the weight of the object. (Ans. 152 N)
not sure how I would set this question up

F = m × g

Now when, a force acts on the object at an angle and in downwards, thus formula becomes:

= N = mg + F sin(x)

Here,

See, as we habe to calculate the weight, which is m × g, thus we will recreate thus formula like thus:

= N = w + F sin(x) --------- [Weight = w]

Now, the solutions becomes easy from here, just put the values:

= N = w + F sin(x)

= 200 = w + 90 × sin(32)

= 200 = w + 90 × 0.55

= 200 = w + 49.5

= 200 - 49.5 = w

= 150.5 = w

I have got my answer but in approx, hope you will not mind. ^^"

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
