Answer:
a)
b)
c)
The estimate is low.
Explanation:
a) Using the energy conservation we have:
we have kinetic energy intially and gravitational potential energy at the maximum height.
b) We can use the equation of the gravitational force
(1)
We have that:
(2)
at the surface G will be:
Now the equation of an object at a distance x from the surface.
is:
Using that dv/dt is vdx/dt and integrating in both sides we have:
c) The difference is:
So the percent difference will be:
The estimate is low.
I hope it helps you!
I belive the answer is D. If i am wrong please call me out for it.
Telescopes use lenses or mirrors to collect and focus waves from the electromagnetic spectrum, including visible light, allowing us to look at celestial objects. By studying the electromagnetic waves given off by objects such as stars, galaxies, and black holes, astronomers can better understand the universe.
Both of them are in big trouble ! I personally would write up each one of them for => no current valid driver's license, => no current vehicle insurance, => no current vehicle emission inspection sticker, => no visible current vehicle, => failure to signal turns, and => speeding in a school zone, since 19.4 m/s is equivalent to 43.4 mph.
Answer:
0.16joules
Explanation:
Using the relation for The gravitational potential energy
E= Mgh
Where,
E= Potential energy
h = Vertical Height
M = mass
g = Gravitational Field Strength
To find the vertical component of angle of launch Where the angle is 22°
h= sin theta
So E = mghsintheta
= 0.18 x 0.98 x 0.253 sin22
=0.16joules
