Problem 73P

CALC A 3.00-kg fish is attached to the lower end of a vertical spring that has negligible mass and force constant 900 N/m. The spring initially is neither stretched nor compressed. The fish is released from rest. (a) What is its speed after it has descended 0.0500 m from its initial position? (b) What is the maximum speed of the fish as it descends?

Step-by-Step Solution:

Solution 73P Step 1: Height of the fish from the ground, h = 0.05 m Therefore, the potential energy of the fish due to gravitational force can be calculated. U = mgh Where, m - mass of the fish g - Acceleration due to gravity h - Height of the fish from the ground Provided, mass of the fish, m = 3.00 kg 2 Therefore, U = 3 kg × 9.8 m/s × 0.05 m = 1.47 J
