Here as we know that there is no loss of energy
so we can say that maximum kinetic energy will become gravitational potential energy at its maximum height
So here we have
![\frac{1}{2}mv^2 = mgh](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7Dmv%5E2%20%3D%20mgh)
here we have
v = 20 m/s
m = 8000 kg
now from above equation we have
![\frac{1}{2}(8000)(20^2) = (8000)(9.8)h](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%288000%29%2820%5E2%29%20%3D%20%288000%29%289.8%29h)
![h = \frac{200}{9.8)](https://tex.z-dn.net/?f=h%20%3D%20%5Cfrac%7B200%7D%7B9.8%29)
![h = 20.4 m](https://tex.z-dn.net/?f=h%20%3D%2020.4%20m)
so maximum height is 20.4 m
That would be false hope this helps
Answer:
<h3>The answer is 40 N</h3>
Explanation:
The force acting on an object can be found by using the formula
<h3>force = mass × acceleration</h3>
From the question
mass = 4 kg
acceleration = 10 m/s²
So we have
force = 4 × 10
We have the final answer as
<h3>40 N</h3>
Hope this helps you
Answer:
J
Explanation:
The daughter moves with greater acceleration backwards because of her weight.
Answer:
Quark
Explanation:
In the past the proton,neutron and electron were believed to be indivisible. Quarks were later discovered to be particles that make up the proton and neutron. Quarks are known as fast moving points of energy and are usually joined to one another through gluons. Neutron has two down quarks and one up quark while proton has two up quarks and one down quark.
