Question

Suppose your mass is 75.0 kg. You step gently off the edge of a high diving platform, so that you essentially start falling from rest towards the Earth. (Ignore air resistance.)

a. During your freefall, which force has the greatest magnitude?

1. the magnitude of the gravitational force of the Earth on you

2. the magnitude of the gravitational force of you on the Earth

3. neither - they are equal

b. During freefall, your downward acceleration will have a magnitude of 9.80 m/s^2. At the same time, what is the magnitude of the Earth's upward acceleration? Please show your work.

Explanation / Answer

a)3. neither - they are equal

b)it will tend to 0

since F=ma

=735 N

mass of earth 5.97*10^-24

so a=F/m

=1.23*10^-22 m/s^2
