Question

If I weigh 741 N on Earth and 5320 N on the surface of anearby planet, what is the acceleration due to gravity on thatplanet? the answer is 70.4 m/s^2. i need a body diagram,the newton application and the net force equations. PLEASE be clear. thanks

Explanation / Answer

mg = 741N ==> m = 741N/9.8m/s^2 = 75.6122kg Let the acceleration due to gravity on the nearby planet be g*. mg* = 5320N ==> g* = 5320N/(75.6122kg) g* = 70.36m/s^2 ......................................… you can also solve in different way: W(earth) = mg ...(1) W(planet) = mg* ...(2) dividing the first equation by the second one , gives:
