Answer:
Mechanical energy, U = 0.247 Joules
Explanation:
Given that,
Spring constant of the spring, k = 234 N/m
Mass, m = 524 g = 0.524 kg
Amplitude, A = 4.6 cm = 0.046 m
To find,
The mechanical energy of the system.
Solution,
We know that the sum of kinetic energy and the potential energy is equal to its mechanical energy. In mass-spring system, it is given by :


U = 0.247 Joules
So, the mechanical energy of the system is 0.247 Joules.
Her magnitude of deceleration on the ice would be 15.126m/s
Horizontal component of force = 100cos(36)= 80.9 N
Answer:
135.3 cm + 93.46cm
= 228.76 cm
So total length of two fish is 228.76
