The radius of a planet is 2400 km, and the acceleration due to gravity at its surface is 3.6 m/s2. What is the mass of the planet?

Explanation:

We can use Newton's Universal Law of Gravitation to solve this problem:

., where is acceleration due to gravity at the planet's surface, is gravitational constant , is the mass of the planet, and is the radius of the planet.

Since acceleration due to gravity is given as , our radius should be meters. Therefore, convert kilometers to meters:

.

Now plugging in our values, we get:

,

Solving for :

.

it would be kevlar ^^

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
