a. A book weighing 12 N is placed in the middle of the shelf. What are the upward forces at X and Y?


b. The book is moved so that it is 40 cm from B. Use moments to calculate the forces at X and Y.

Answer 1

1. force =m×a=40=200×a=a=200-40=160m/second sguared

Step-by-step explanation:

always accerelation it measures in m/second sguared.
