Homework Help: Looks good? f = Gm1m2/R2

  1. Jun 17, 2005 #1
    how does this look, fun prob., need help on the 2nd part:

    wat is the force that a 60 kb girl has on a 75 kg man, when they are 50 cm apart:

    f = GM1m2/R2 = F = (6.67e-11)(75)(60)/(.50)^2
    = 1.2e-6 N

    second part:
    how fast will man accelerate towards girl??

    same formala?

    What's the relationship between the force and the acceleration (assuming constant mass) ?You'll see it's only a simple division.Oh,and that 60Kg girl is fat...:yuck:
