A clock is designed that uses a mass on the end of a spring as a timing mechanism. If the oscillation time needed is exactly one second, what is the spring constant required if the mass is 1.3 kg

The value is  

Explanation:

From the question we are told that

   The  mass is  

   The needed oscillation time is    

 Generally the spring constant is mathematically represented  as

=>      

=>      

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be
