Suppose that you are swimming in a river while a friend watches from the shore. In calm water, you swim at a speed of 1.25 m/s .
belka [17]

Answer:

Your friend sees you moving at 0.25 m/s upstream.

Step-by-step explanation:

Remember that relative velocity is the velocity of an object in relation to another object. In this example, your friend sees you moving with respect to the river with a relative velocity (Vr) of:

Vr = Yor Velocity (Vy) - The river Velocity (Vriver) =

Vr = 1.25 m/s - 1 m/s = 0.25 m/s

I hope my answer helped you.

A box on a 20 degree incline is shown with vectors radiating from a point in the center of the box. The first vector points up a
Finger [1]

The images to solve this problem is in the attachment.

Answer: F_{fs} = 671.0 N; F_{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:

F_{fs}  = F_{gx} and F_{N} = F_{gy}

Using trigonometry, shown in the second attachment, the values for each force are:

  • Force of Static Friction

sin 20° = \frac{F_{gx} }{F_{g} }

F_{gx} = F_{g}. sin(20)

F_{gx} = 735.0.913

F_{gx} = 671.0

  • Normal Force

cos 20° = \frac{F_{gy} }{F_{g} }

F_{gy} = F_{g}. cos (20)

F_{gy} = 735.0.408

F_{gy} = 300

The force of static friction is 671N and normal force is 300N
