After the sun spun to light, the planets of the solar system began to form. But it took another hundred million years for Earth's moon to spring into existence. There are three theories as to how our planet's satellite could have been created: the giant impact hypothesis, the co-formation theory and the capture theory.

A force is applied to a particle along its direction of motion. At what speed is the magnitude of force required to produce a gi
krek1111 [17]

Answer:

Explanation:

The detailed steps are as shown below

  • Recalling from F = ma
  • a = F/m
  • but magnitude of force F = √ [ 1 - v²/c²]

but acceleration twice as great as the force required to produce the same acceleration;

  • 2m = m / √[ 1 - v²/c²]
  • 2 = 1 / √ [ 1 - v²/c²]
  • square both sides ;

4 = 1 / [ 1 - v²/c²]

1/4 = 1 - v²/c²

v²/c² = 3/4

v/c = √ [3/4]

v = 0.87c

but speed of light c = 3 x 10^8m/s

v = speed of the particle =  0.87( 3 x 10^8m/s)

v = 2.61m/s
