A 14.6 g mass is attached to a horizontal spring with a spring constant of 15.7 N/m and released from rest with an amplitude of 29.8 cm. What is the speed of the mass when it is halfway to the equilibrium position if the surface is frictionless

v = 8.46 m/s

Explanation:

Given that,

Mass of the object, m = 14.6 g

Spring constant of the spring, k = 15.7 N/m

It is released from rest with an amplitude of 29.8 cm.

We need to find the speed of the mass when it is halfway to the equilibrium position if the surface is frictionless.

We can use the conservation of energy in this case. Let v be the speed of the mass. So,

Substitue all the values in the above expression.

So, the speed of the mass is equal to 8.46 m/s.

s the environmental science is a broader field that incorporates many elements of earth and life sciences, whereas ecology is usually more focused on how organisms interact with each other and their surroundings, and often on a very specific population of living things. soo yea

explanation:

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.
