Answer:

300 cos 30 = 40 a + 40 * .2 * 10

Total force = mass * acceleration + frictional force

260 = 40 a + 80

a = 180 / 40 = 4.5 m/s^2

Check:

15 a + 15 * 10 * .2 = T acceleration of 15 kg block (assuming a = 4.5)

T = 15 (4.5) + 30 = 97.5 force required to accelerate 15 kg block

260 - 97.5 = 162.5 net force on 25 kg block

162.5 = 4.5 (25) + 25 * 10 * .2

162.5 = 112.5 + 50 = 162.5

4.5 m/s^2 checks out as correct

The planet Mercury takes 0.24 sidereal years to go around the sun. What is the distance from the center of Mercury to the center

lyudmila [28]

Answer:

5.77×10¹⁰ m

Explanation:

From the question,

Applying

Kepler's third law

P² = d³...................... Equation 1

Where P = Planet's period, d = distance between the center of the planet and the sun.

make d the subject of the formula n equation 1

d = $\sqrt[3]{P^{2} }$ .................. Equation 2

Given: P = 0.24 sidereal.

Substitute the value of P into equation 2

d = $\sqrt[3]{0.24^{2} }$

d = 0.386 Au

d = 0.386×1.496×10¹¹

d = 5.77×10¹⁰ m
