Help!! Marvin Martian is standing on planet Potatoine. Potatoine has the following physical
data:
Radius: 7.4x106 m

If Marvin's mass is 110 kg, calculate his weight on Potatoine.

Arocket starts from rest and moves upward from the surface of the earth. for the first 10.0 s of its motion, the vertical acceleration of the rocket is given by ay = 12.80 m/s32t, where the +y-direction is upward. (a) what is the height of the rocket above the surface of the earth at t = 10.0 s? b) what is the speed of the rocket when it is 325 m above the surface of the earth?
