C because gravity is holding everything down
Yhuihoifjhh <span>F = Gm1m2 / r^2
if the masses are doubled then the force is increased by a factor of 4
if the distance is doubled the force is decreased by a factor of 1/ 2^2
the net result is no change in force</span>
Answer:
x = 7226.94 m
y = 1677.4 m
Explanation:
This is a classic problem of a parabolic move. Let's analyze the given data.
The speed is 300 m/s but it's fired at 55°, so the x and y component of the speed would be:
Vx = 300 cos55 = 172.07 m/s
Vy = 300 sin55 = 245.75 m/s
Now, to get the x and y components of the shell, we need to apply the following expressions:
X = Xo + Vx*t (1)
Y = Yo + Vy*t - 1/2 gt² (2)
Xo and Yo is 0, and we already have the speed in x and y, so the components are:
X = 0 + (172.07)(42)
<h2>
X = 7226.94 m</h2>
For the y component:
Y = 0 + (245.75)(42) - 1/2 (9.8)(42)²
Y = 10321.5 - 8643.6
<h2>
Y = 1677.4 m</h2><h2>
</h2>
Hope this helps
The thin atmosphere of Mars is thought to be due to the planet's lack of a magnetic field, which has allowed the Solar wind to blow away much of the gas the planet once had. Venus, despite still having a thick atmosphere of CO2, surprisingly has a similar problem
