Calculate the gravitational force on a 6.50x10^2 kg thats is 4.15x10^6 above the surface of the earth?

2352 N

Explanation:

The gravitational force exerted by the Earth on an object is given by

(1)

where

is the gravitational constant

m is the mass of the object

is the Earth's mass

r is the distance between the object and the Earth's center

In this problem, we have an object of mass . Its distance from the Earth's center is given by its distance above the surface plus the Earth's radius, R:

Substituting into equation (1), we find

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.

formula.

example:

given values:

mass = 0.3 kg.

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
