It’s supposed to be gamma, what are your other options
It's either A or B because it starts off as nuclear energy.
When the resistance decreases, the current increases.
Answer:
the maximum speed of the ball is 12.65 m/s
Explanation:
Given;
mass of the ball, m = 40 g = 0.04 kg
spring constant, k = 25 N/m
Apply the principle of conservation of energy;
The Elastic potential energy of the spring will be converted into Kinetic of the ball;

Therefore, the maximum speed of the ball is 12.65 m/s
