Pulling a dog on a skateboard A child puts their puppy on a skateboard and attaches a rope to the skateboard in order to give the puppy a ride. At time

, the child starts pulling on the rope. They are pulling at an angle of

above the horizontal. Once the child reaches top speed (at time

), they run at a constant rate until a time

. At that time, the child's parent cautions the child to slow down, so the child gradually comes to a stop. Assume the child, the skateboard, and the puppy are all moving to the left. Since they are moving together, they will all have the same velocity and acceleration.motion. The contact interaction between the puppy and the skateboard may have both vertical and horizontal components. We can assume the contact interaction between the skateboard and the floor has only a vertical component (that is, there is no friction between the skateboard wheels and the floor). Use the diagram below with the labeled vector directions to answer the questions in this set.Fill in the Blank 5 points Between times

and

, while they are all moving at constant speed, determine the direction of the following forces. The net force that is acting on the skateboard:

1 The net force that is acting on the puppy:

The horizontal contact force of the skateboard on the puppy:

The pulling force of the rope on the skateboard:

The horizontal contact force of the puppy on the skateboard:
