An egg is thrown downward at 3.15 m/s from the roof of a 27.5 m tall building. What is the final velocity of the egg, just before it hits the ground?

Answer: 23.44 m/s

Explanation:

To find the final velocity of the egg, we can use the following kinematics equation:

v² = v₀²+2ad, where:

  • v is the final velocity
  • v₀ is the initial velocity
  • a is the acceleration
  • d is the displacement

We are given:

  • v₀ = 3.15 ms
  • a = 9.81 m/s² (acceleration due to gravity since the object is in freefall)
  • d = 27.5 m

Let's plug these values into the formula:

v² = 3.15² + 2(9.81)(27.5)

Solve for v:

v = 23.44 m/s

The final velocity of the egg is 23.44 m/s.
