Answer:
Step-by-step explanation:
Find the velocity of Tim and Stan, by dividing the distance between the time:
The distance that Stan and Tim travel in 5 minutes is equal to their respective velocity multiplied by the time.
The answer to the question is the difference in miles traveled by Stan minus those traveled by Tim.
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
