If I weigh 700 N on Earth and 5300 N on the surface of a nearby planet Mars, what is the acceleration due to g

Two forces act on a 55 kg object. One force has magnitude 65N directed 59° clockwise from the positive x axis, and the other has a magnitude 35 N at 32° clockwise from the positive y axis. What is the magnitude of this object’s acceleration?



If I weigh 700 N on Earth and 5300 N on the surface of a nearby planet Mars, what is the acceleration due to gravity on Mars?


A 65 kg ice skater pushes off this partner and accelerated backwards at 1.3 m/s2. If the partner accelerated in the opposite direction at 2.0 m/s2 what is the mass of the other skater? (Assume that frictional forces are negligible.)



Can anyone answer them in detail?
Thank you!

1. (5300/700) x 9.8 = 74.2m/sec^2.
2. (65 x 1.3) = 84.5kg/m/sec.
(84.5/2) = 42.25kg.

Do you really need detail? Pretty well self explanatory, I think...?

The acceleration due to gravity on Mars is 74.275714285714285714285714285714 N/Kg
Acceleration due to gravity on Earth is 9.81N/Kg
700 / 9.81 = 71.355759429153924566768603465851
5300 / 71.355759429153924566768603465851 = 74.275714285714285714285714285714 N/Kg
This is just a question. These planets are of a similar size.
Hope this helps
Dougie :)
