Estimate how much energy would be deposited into the Earth if it is hit by a ten tonne meteor traveling on an orbit around the Sun with a semi-major axis of 3.0 A.U. Note: in order to hit the Earth this meteor can not be in a circular orbit. Consider two cases: At the point of impact (a) the meteor is traveling parallel and in the same direction as the Earth’s orbit and (b) the meteor is traveling parallel and...

How much gravitational potential energy must a 3140-kg satellite acquire in order to attain a geosynchronous orbit? The answer to the above question is 1.67x10^11 J. How much kinetic energy must it gain? Note that because of the rotation of the Earth on its axis, the satellite had a velocity of 467 m/s relative to the center of the Earth just before launch. Doing a 1/2mv^2 doesn't get the correct answer. The law of conservation of energy would state that...

Mr. Lake pushes a block of mass of 100kg with a force of 120N across a smooth surface. Mr. Earle pushes the same block in the opposite direction with an unknown force. 1) If the block accelerates at a rate of 0.7m/s^2, how much force was Mr. Earle pushing with? (Just give me the magnitude; don't worry about the direction) 2) If this block is pushed over a distance of 4m, how much work does Mr. Lake do on the...
