Newton’s First Law of Motion - if an object is at rest, it takes un-
balanced forces to make it move. Conversely, if an object is moving
it takes an unbalanced force to make it change it’s direction or speed.
Newton was the first to see that such apparently diverse phenomena as a satellite moving near the Earth's surface and the planets orbiting the Sun operate by the same principle: Force equals mass multiplied by acceleration, or F=ma.
By Newton's second law, we have

So, in order to give a 0.15kg body an acceleration of 40m/s^2, you need a force of

Because it can dissolve almost anything.
The speed and temperature have nothing to do with solubility.
They will use pulleys or something with a wheel and axle
