Question

If mass if a manis60kg.calculate his weight on earth and moon if the values of gram are 9.8 meter/second square and 1.6 meter/second square in eathand moon's surface respectively.

Answer 1

Step-by-step explanation:

w = mg, and no matter where we go, our masses will never change. Our weight does, however, depending upon the gravity of where we are. Let's first find the weight of the man on earth, where the pull of gravity is -9.8 m/s/s:

w = (60)(-9.8) so

w = 590 N rounded from 588. It's negative because weight is a downward value (whereas Normal force is the upward value of this measurement, making Normal force the positive of this same number)

Now for the moon, where gravity is 1.6 m/s/s:

w = (60)(-1.6) so

w = -96 N
