Answer:5.13333333...
Explanation: 7.7 is the distance and an hour and a half is the average speed. You would have to divide the total distance by the total time. So it would be 7.7 divided by 1.5 which would equal 5.13333333333...
Blood is an incompressible fluid. Hope this helps!
I think it is D because gas particles move the fastest but if not then it is A
Answer:
<em>The range is 15.15 m and the time in the air is 1.01 s</em>
Explanation:
<u>Horizontal Motion</u>
When an object is thrown horizontally (with angle 0°) with a speed v from a height h, it follows a curved path ruled exclusively by gravity until it eventually hits the ground.
The range or maximum horizontal distance traveled by the object can be calculated as follows:

To calculate the time the object takes to hit the ground, we use the equation below:

The cannon is shot from a height of h=5 m with an initial speed of v=15 m/s. The range is calculated below:

d = 15.15 m
The time in the air is:

t = 1.01 s
The range is 15.15 m and the time in the air is 1.01 s
