Convert 220 lb to kg.

220/2.2 = 100kg.

W = Fd (In this case, F is the weight)
W = (100)(2)
W = 200J

P = W/t
P = (200)/(1.2)
P = 166.67W

lbvjy [14]

Answer: 8.242 × 10 exp -8 N

Explanation: F = G *m* M/r^2

r = √(13-5)^² + (51-15)^² + (0-0)²

r = 8; the distance between the masses

G =6.673 × 10 -¹¹ Nm²kg-²

F = gravitational force of attraction of m(51kg) on M {1550kg)
