Assume the centers of mass of the cars are 25m apart :

F = G m1m2 / R2

G = 6.673 x 10-11

F = (6.673 x 10-11) (1,000)(1,000)/(25)2 = 0.0000001068 newton (rounded)

F = G M1M2/R2

G = 6.673 x 10-11 m3/kg-sec2

M1 = 1,050 kg

M2 = 1,050 kg

R = 31 m

F = (6.673 x 10-11) x (1, 050) x (1,050)/(31)2 = 7.655 x 10-8 newton = about 0.000000276 ounce
