A 0.2-kg block is held in place by a force that results in a 0.10-m compression of a spring beneath the block. The spring constant is 1.0 × 102 N/m. Assuming the mass of the spring is negligible compared to that of the block, to what maximum height would the block rise if the force were removed.?

Respuesta :

Answer:

h = 0.255 meters

Explanation:

It is given that,

Mass of the block, m = 0.2 kg

Compression in the spring, x = 0.1 m

Spring constant of the spring, [tex]k=10^2\ N/m[/tex]

Let h is the maximum height reached by the block if the force were removed. Using the conservation of energy of the spring mass system as :

[tex]mgh=\dfrac{1}{2}kx^2[/tex]

[tex]h=\dfrac{1}{2mg}kx^2[/tex]

[tex]h=\dfrac{1}{2\times 0.2\times 9.8}\times 100\times (0.1)^2[/tex]

h = 0.255 meters

So, the maximum height reached by the block is 0.255 meters. Hence, this is the required solution.
