Answer:

Force required to change velocity = 2.5 kN

Explanation:

Force required = Mass of box x Acceleration of box

Acceleration of box = Change in velocity of box / Time.

Mass of box, m= 1000 kg

Acceleration of box, a = (10 - 5)/2 = 5/2

= 2.5 m/s²

Force required = ma

= 1000 x 2.5 = 2500 N = 2.5 kN

Force required to change velocity = 2.5 kN

Two planets have the same surface gravity, but planet b has twice the radius of planet

vampirchik [111]

Planet A;
m = the mass
Let r = the radius

Planet B:
Let M = the mass
The radius is 2r (twice the radius of planet A)

The surface gravitational acceleration of planets A and B (they have the same surface gravity) are
$g= \frac{Gm}{r^{2}} \, and \, g= \frac{GM}{(2r)^{2}} \\\\ m= \frac{M}{4} \\\\ M=4m$

Answer: The mass of planet B is 4m.
