The images to solve this problem is in the attachment.
Answer: 
= 671.0 N; 
= 300 N
Step-by-step explanation: From the image in the attachment and knowing that the box is in equilibrium, i.e., the "sum" of all the forces is 0, it is possible to conclude that:
= 
and = 
Using trigonometry, shown in the second attachment, the values for each force are:
sin 20° = 
= 
. sin(20)
= 735.0.913
= 671.0
cos 20° = 
= . cos (20)
= 735.0.408
= 300
The force of static friction is 671N and normal force is 300N
Answer:
Step-by-step explanation:
a)
The mean for ground floor is 20.67
The mean for balcony is 15.8
b)
the difference between the means is ground floor - balcony
20.67 - 15.8 = 4.87
You can talk about it yourself for part c
.81 and 2.63 if you divide them
V=xyz
V=0.75(2.5)1.25
V=2.34375 ft^3 or if you want the fraction..
V=2 11/32 ft^3
