Answer:
The value is 
Explanation:
From the question we are told that
The weight of the horizontal solid disk is
The radius of the horizontal solid disk is
The force applied by the child is
The time considered is 
Generally the mass of the horizontal solid disk is mathematically represented as

=> 
=> 
Generally the moment of inertia of the horizontal solid disk is mathematically represented as

=>
=> 
Generally the net torque experienced by the horizontal solid disk is mathematically represented as

=> 
=> 
=> 
Gnerally from kinematic equation we have that

Here
is the initial angular velocity velocity of the horizontal solid disk which is 
So

=>
Generally the kinetic energy is mathematically represented as

=> 
=> 
The answer is the first one, Daniela has a 5 meter head start but leonard caught up to her.
The frequency of oscillation on the frictionless floor is 28 Hz.
<h3>
Frequency of the simple harmonic motion</h3>
The frequency of the oscillation is calculated as follows;
f = (1/2π)(√k/m)
where;
- k is the spring constant
- m is mass of the block
f = (1/2π)(√7580/0.245)
f = 28 Hz
Thus, the frequency of oscillation on the frictionless floor is 28 Hz.
