    On Planet X, a 70 kg object can be lifted by a force of 400 N

    On Planet X, a 70 kg object can be lifted by a force of 400 N Suppose your car was taken to Planet X. If the car has a mass of 1500 kg, what would its weight be? W=mg a=W/m a=400/70 a=5.7m/s/s W=1500*5.7 W=8550N on the site http://library.thinkquest.org/10796/ they say that the answer is...
