A4.00-kg mass is attached to a very light ideal spring hanging vertically and hangs at rest in the equilibrium position. the spring constant of the spring is 1.00 n/cm. the mass is pulled downward 2.00 cm and released. what is the speed of the mass when it is 1.00 cm above the point from which it was released?

|v| = 8.7 cm/s

Explanation:

given:

mass m = 4 kg

spring constant k = 1 N/cm = 100 N/m

at time t = 0:

amplitude A = 0.02m

unknown: velocity v at position y = 0.01 m

1. Finding Ф from the initial conditions:

2. Finding time t at position y = 1 cm:

3. Find velocity v at time t from equation 2:

there are no components of a physical goal mentioned on the list of choices that you've provided.
