Objects 1 and 2 attract each other with a gravitational force

The new gravitational force of the two objects will be 432 N.

The given parameters:

  • <em>Force between object 1 and object 2, F = 18 N</em>

  • <em>Let the mass of object 1 = m1</em>
  • <em>Let the mass of object 2 = m2</em>
  • <em>Let the distance between the two object = r</em>

The gravitational force between the two objects is calculated by applying Newton's law of universal gravitation;

F = \frac{Gm_1m_2}{r^2} \\\\G = \frac{Fr^2}{m_1m_2}\\\\G = \frac{Gm_1m_2}{r^2} \\\\G = \frac{18r^2}{m_1m_2}

  • when the mass of the object 1 = 2m1
  • mass of the object 2 = 3m2
  • distance between the two object = ¹/₂r

\frac{18r^2}{m_1 m_2 } = \frac{F_2(\frac{1}{2}r)^2 }{2m_1 \times 3m_2} \\\\\frac{18r^2}{m_1 m_2 } = \frac{F_2 \times r^2}{4 \times 2m_1 \times 3m_2} \\\\\frac{18r^2\times 4 \times 2m_1 \times 3m_2}{m_1 m_2\times r^2 } = F_2\\\\432 \ N = F_2

Thus, the new gravitational force of the two objects will be 432 N.

NARA [144]

Answer:

90 hp

Explanation:

Power = work / time

P = ½ (1500 kg) (25 m/s)² / 7.0 s

P = 67,000 W

P = 90 hp
