Answer 1

Weight of the person is W = 150 lbs Using Ilbs = 4.45 N Weight of the person in Newtons is We 150 x4.45 - 667.5 N The mass of the person is | m- A = 667.5 N 4 g 9.81 m/s2 - The weight of the person on Sun is the force applied by sun on the person located at the surface of the Sun. W = GMsun m [using F GMM] - Run Wc (6.67x10 ") x (1.989x1050) x (68.0) (6.955 x108)? W= 18650 N W= 18650 x 1 lbs [using IN= 21.45 os] 4.45 W= 18650 m plast postars Listas en 1 = 2оор , -) (US= 1 2000 P 2000 IW=2 tons
