Set local ground level to 700 ft, and record the inches of mercury.
1 answer:
The main way in which an altimeter measures the altitude of an object is by calculating the location's air pressure.
<h3>What is an Altimeter?</h3>This refers to the instrument that is used to measure the altitude of an object when it is at a fixed level.
Hence, we can see that an altimeter should NOT be confused with a barometer, because although they both measure pressure, a barometer calculates the change in air pressure and elevation based on available weather.
Please note that your question is incomplete so I gave you a general overview to help you get a better understanding of the concept.

Answer:
The distance by the ball clear the crossbar is 1.15 m
Explanation:
Given that,
Distance = 44 m
Speed = 24 m/s
Angle = 31°
Height = 3.05 m
We need to calculate the horizontal velocity
Using formula of horizontal velocity
Put the value into the formula
We need to calculate the vertical velocity
Using formula of vertical velocity
Put the value into the formula
We need to calculate the time
Using formula of time
Put the value into the formula
We need to calculate the vertical height
Using equation of motion
Put the value into the formula
We need to calculate the distance by the ball clear the crossbar
Using formula for vertical distance
Put the value of h
Hence, The distance by the ball clear the crossbar is 1.15 m
