As an object falls toward earth, the potential energy of the object : Decreases
Here's the formula for the Potential energy :
E = Em + Ek + Eg
m = mass
= k kinetic
g = gravity
As the potential energy falls toward earth, the Eg became 0, which will decrease its amount
Answer:
567.321nm
Explanation:
See attached handwritten document for more details
Answer:
754.8 m
Explanation:
The centripetal acceleration is given by
where v is the speed of the airplane and r is the radius of the loop.
We can rewrite the speed of the airplane as the ratio between the length of the circumference () and the time taken:
Substituting in the formula of the acceleration, we have
Re-arranging the formula and putting the numbers of the problem into it, we can find the radius of the loop, r:
