Question

a coin is flicked horizontally off a table. which of the following statements about its velocity is true just before it hits the ground? its velocity is the same as its initial horizontal launch velocity. it has a vertical velocity but no horizontal velocity. both its horizontal and vertical velocity are zero. it has both a horizontal and vertical velocity.

Explanation:

Step1: Analyze horizontal motion

There is no horizontal - direction force (ignoring air resistance), so horizontal velocity remains constant.

Step2: Analyze vertical motion

Under the influence of gravity, the coin has a downward acceleration. Starting from rest vertically, it gains a vertical velocity as it falls.

Answer:

It has both a horizontal and vertical velocity.
