The answer explains how to calculate the velocity of an object dropped from a height and how to determine its velocity relative to the Earth.
Velocity when it strikes the floor:
The velocity of an object dropped from a height can be calculated using the equation: v = √(2gh), where v is the final velocity, g is the acceleration due to gravity (9.81 m/s²), and h is the height of the drop. In this case, when the coin strikes the floor 1.50 m below its point of release, it has a velocity of approximately 17.15 m/s relative to the Earth.
Velocity relative to the Earth:
When measured relative to the Earth, the velocity of the coin is equal to its velocity added to the velocity of the plane. Therefore, the velocity of the coin relative to the Earth is 277.15 m/s.
