9. An object of mass 88.444 kg is sliding on a horizontalsurface. Calculate the normal force exerted bythe surface on the object. (1 point)A. O 270.156 NB. O 659.934 NC. O1289.839 ND. O1165.906 NE. O866.751 N[

9.
m =mass = 88.444 kg
g= gravity = 9.8 m/s^2
Normal (N) force is equal to weight (W)
W= N
W = M x g = 88.444 kg x 9.8 m/s^2 = 866.751 N
Normal force: 866.751 N (option E)
