Ten days after it was launched toward mars in december 1998, the mars climate orbiter spacecraft (mass 629 kg) was 2.87×106km from the earth and traveling at 1.20×104km/h relative to the earth. at this time, what were the following. (a) the spacecraft's kinetic energy relative to the earth j (b) the potential energy of the earth-spacecraft system j

3494444444.44444 J

-87077491.39453 J

Explanation:

M = Mass of Earth =

G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²

R = Radius of Earth =

h = Altitude =

m = Mass of satellite = 629 kg

v = Velocity of spacecraft =

The kinetic energy is given by

The spacecraft's kinetic energy relative to the earth is 3494444444.44444 J

Potential energy is given by

The potential energy of the earth-spacecraft system is -87077491.39453 J

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
