10,500 J of GPE, weight 539 N, how tall is the hill you are sitting on?

maks197457 [2]

Answer:

19.48 m

Explanation:

Gravitational potential energy = mgh

Current weight = 539 N

Weight = mg = 539 N

Mass x Acceleration = 539 N

Mass x 9.81 = 539

Mass = 54.94 kg

Gravitational potential energy = mgh = 10500 J

54.94 x 9.81 x h = 10500

h = 19.48 m

Height of sitting = 19.48 m

A bag of potatoes has a mass of 2.5 kg. What is its approximate weight on Earth?

ad-work [718]

Weight = m (mass) * g (acceleration due to gravity)

g = 9.80 m/s^2
m = 2.5 kg = 2,500 g

Weight = 2,500 g * 9.80 m/s^2
Weight = 24,500 N

A satellite is in a circular Earth orbit of radius r. The area A enclosed by the orbit depends on r2 because A = πr2. Determine

Salsk061 [2.6K]

Answer:

a. $T=r^{3/2}$

b. $K=\frac{1}{r}$

c. $v=\frac{1}{\sqrt{r}}$

d. $v=\sqrt{r}$

Explanation:

To make analysis about the satellite circular earth the depends or r and A

$T^2=\frac{4\pi}{GM}*r^3$

$K=\frac{GM*m}{2*r}$

$T^2=r^3$

$T=r^{3/2}$

$K=\frac{GM*m}{2}*\frac{1}{r}$

$K=\frac{1}{r}$

$K=\frac{1}{2}*m*v^2$

$v^2=\frac{2*K}{m}=\frac{2*Gm*m}{2*m*r}$

$v=\frac{1}{\sqrt{r}}$

$v=\sqrt{2*GMr}$

$v=\sqrt{r}$
