Question

A stone thrown with a certain speed (v) from a building 50m high. The stone will hit the ground with maximum speed if it is thrown?

1) at an angle of 45 degrees
2) straight upwards
3) straight downwards
4) horizontally

Answer 1

The stone will hit the ground with the maximum speed if it is thrown horizontally.

Step-by-step explanation:

The stone will hit the ground with the maximum speed if it is thrown horizontally. When a stone is thrown horizontally, its initial vertical velocity is zero and it only experiences the downward force of gravity. This means that all of the initial speed is converted into horizontal motion, resulting in the maximum speed.
