Question
A weight of 450 N rests upon a vertical spring whose cale is 140 N/mm. The spring is then pressed down 150mm farther by an added pressure of 21 kN. If this added pressure is then released suddenly, what will be the velocity of the 450 N weight 1.50m above the depressed position.
A weight of 450 N rests upon a vertical spring whose scale is 140 N/mm. The spring is then pressed down 150mm farther by an added pressure of 21 kN. If this added pressure is then released suddenly, what will be the velocity of the 450 N weight 1.50m above the depressed position. 450 N HINT: The spring is initially compressed by 450N/(140N/mm)=3.21mm!
