Question #226700

An object is released from height of 72 feet and is given an initial horizontal velocity of 22 ft/s. When the object strikes the ground, how far has it travelled in the horizontal direction?

Expert's answer

The distance travelled by the object in the vertical direction is:

If the height is and is the gravitational acceleration, then the falling time will be:

Object's horizontal speed has not been changed with time. Thus, the distance in the horizontal direction travelled in time of falling will be:

where . Thus, obtain:

**Answer. **48.6 feet.
