Here it is. It was too much to type on a phone....
Answer:
U = 1000 J
Explanation:
By the conservation of energy, potential energy is converted into kinetic energy when the ball falls from a height.
U = Energy (in Joules)
m = mass (in kg)
v = velocity in (m/s)
g = acceleration due to gravity (in m/s^2)
h = height (in m)
Let's use as we have the values given.
Carbon-14 is a naturally occurring carbon isotope.
Carbon-14 has a known half-life.
Carbon-14 is present in all living organisms.
Answer:
(a) = 3910
(b) = 5181
(c) = 2762955 m
Explanation:
Using equations of uniformly accelerated motion:
Equations:
-
-
(a) Using equation 1:
⇒ Because it upward from rest
(b) Using equation 1:
⇒ Because is the is the initial speed in the movement before changing acceleration
(c) Using equation 2:
⇒ and Because it upward from rest
⇒
