Avertical spring (ignore its mass), whose spring constant is 594-n/m, is attached to a table and is compressed down by 0.196-m. what upward speed (in m/s) can it give to a 0.477-kg ball when released?

Speed, v = 6.91 m/s

Explanation:

Given that,

Spring constant, k = 594 N/m

It is attached to a table and is compressed down by 0.196 m, x = 0.196 m

We need to find the speed of the spring when it is released. Here, the elastic potential energy is balanced by the kinetic energy of the spring such that,

v = 6.91 m/s

So, the speed of the ball is 6.91 m/s. Hence, this is the required solution.

option number c is the right answer.
