Final answer:
An object released from the equilibrium position with a downward velocity of 7ft/s experiences a constant acceleration due to gravity. The acceleration is typically represented as g = 32ft/s². By using the kinematic equations, we can calculate the object's motion in the vertical direction.
Step-by-step explanation:
When an object is released from the equilibrium position with a downward velocity of 7ft/s, it is in free fall and experiences a constant acceleration due to gravity. The acceleration due to gravity is typically represented by the symbol g and has an average value of 32ft/s² or 9.81m/s². In this case, we can assume g = 32ft/s².
To calculate the object's motion, we can use the kinematic equations for motion in a uniform gravitational field. Since the object is moving vertically, we only need to consider the acceleration in the y-direction. The acceleration, ay, is equal to -g, or -32ft/s².
Using these values, we can apply the kinematic equations to determine the object's displacement, velocity, and time at any given point.
