Answer:
the energy increases 4 times
Explanation:
A spring has an elastic potential energy that is given by the expression
K_e = ½ K (x-x₀)²
where x is the distance from the equilibrium point and k is the return constant
if the spring is stretched at x-x₀ = 2x₀, the energy value
K_e = ½ k (2x₀)²
K_e = ½ k 4 x₀²
K_e = 4 (½ k x₀²)
= 4
therefore the energy increases 4 times

Answer:
None
Explanation:
Force, F is given by ma where m is the mass of an object and a is acceleration
Acceleration is the rate of change in velocity per unit time. Since skaters with mass of 75 kg and 50 kg are moving at a constant speed, there is no acceleration hence F=50*0=0 and F=75*0=0
For skater of 45 kg, he is at rest to mean the initial and final velocitu of the skater is zero hence no acceleration, the force will be 45*0=0
Therefore, none of the skaters will experience a greater net force.
