Explanation:
its hard to explain its very complex but its so they can function properly
Answer:
40mph
Explanation:
1st leg DATA:
time = 3 hrs ; speed = r mph ; distance = 3r miles
------------
2nd leg DATA:
speed = r mph ; distance = 12 miles
--------------------------------
3r + 12 = 132
3r = 120
rate = 40 mph
Kinetic Energy is calculated by KE= 1/2mv2
Answer:
It changes into a completely different element
Answer:

Explanation:
Hello,
In this case, since the acceleration in terms of position is defined as its second derivative:

The purpose here is derive x(t) twice as follows:

Thus, the acceleration turns out 4.8 meters per squared seconds.
Best regards.
