Answer:

F = 120 N

Explanation:

If we ASSUME that the circle is horizontal

Fc = mv²/R = 0.309(12.9²)/0.429 = 119.8617... N

There would also be the vertical force of weight

Fg = mg = 0.309(9.81) = 3.03129 N

which is small enough to ignore, but we can check

F = √(3.03129² + 119.8617² = 119.9000... N

Yup, ignorable.

You wish to place a spacecraft in a circular orbit around the earth so that its orbital speed will be 4.00×103m/s. What is this

Levart [38]

Answer:

The radius of orbit= $2.49\times 10^7 m$

Explanation:

We are given that

Orbital speed= $4.00\times 10^3$ m/s

We have to find the radius of orbit of spacecraft.

We know that

Gravitational constant= $6.67\times 10^{-11}m^3/kgs^2$

Mass of earth= $5.972\times 10^{24} kg$

Orbital speed= $\sqrt{\frac{GM}{r}}$

Where G= Gravitational constant

M=Mass of earth

r=Radius of orbit

Substitute the values in the formula

$4\times 10^3=\sqrt{\frac{6.67\times 10^{-11}\times 5.972\times 10^{24}}{r}$

Squaring on both sides

$16\times 10^6=\frac{6.67\times 10^{-11}\times 5.972\times 10^{24}}{r}$

$r=\frac{6.67\times 10^{-11}\times 5.972\times 10^{24}}{16\times 10^6}$

$r=2.49\times 10^7 m$

Hence, the radius of orbit= $2.49\times 10^7 m$
