The planet Jupiter revolves around the Sun in a period of about 12 years (3.79 × 108 seconds). What is its mean distance from th

givi [52]

As we know that gravitational force of Sun will provide the centripetal force to all planets

so here we will have

$F_g = F_c$

$\frac{GMm}{r^2} = m\omega^2 r$

here we know that

$\omega = \frac{2\pi}{T}$

$\omega = \frac{2\pi}{3.79 \times 10^8}$

$\omega = 1.66 \times 10^{-8}$

now from above equation

$\frac{GM}{r^2} = \omega^2 r$

$\frac{GM}{\omega^2} = r^3$

$\frac{(6.67 \times 10^{-11})(1.99\times 10^{30})}{(1.66\times 10^{-8})^2} = r^3$

$r = 7.8 \times 10^{11} m$

An empty train car of mass 2.0 x 10^4 kg coasts along at 10 m/s. A 3000-kg boulder is suddenly dropped vertically into the car.

Zepler [3.9K]

Answer:8.69 m/s

Explanation:

Given

mass of Empty train $m=2\times 10^4 kg$

velocity of car $v=10 m/s$

mass of Boulder $M=3000 kg$

Since no External force is acting therefore conserving Momentum

Train and boulder moves with same velocity after collision

$m v=(M+m)v'$

$2\times 10^4\times 10=(2\times 10^4+3000)v'$

$v'=\frac{20,000\times 10}{23000}$

$v'=8.69 m/s$
