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

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

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

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

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

aleksklad [387]

Explanation:

v=140 m/s

t=50s

u=0

change of velocity = v-u

140-0=140 m/s

for acceleration:

from Newton's first law of motion:

v=u+at

140=0+a50

50a=140

a=140/50

a=2.8 m/s²
