A block with a mass of 0.28 kg is attached to a horizontal spring. The block is pulled back from its equilibrium position until the spring exerts a force of 1.0 N on the block. When the block is released, it oscillates with a frequency of 1.2 Hz. How far was the block pulled back before being released?

Answer:

Step-by-step explanation:

For spring


n=\sqrt{(k)/(m) }

where n is frequency of oscillation and k is force constant and m is mass

Putting the values


1.2=\sqrt{(k)/(.28) }

k = .4032 N/m

F= k x

where F is force , k is force constant and x is extension

Putting the given values

1 = .4032 x

x = 2.48 m
