Newton’s Third Law of Motion

The horse pulls the cart and the cart pulls the horse in response as per Newton third law. So the big question is, “Don’t the two forces cancel each other? How does the cart accelerate?”

Question

1. The figure below represents a cart viewed from above being pulled by two children
and experiencing a frictional force. Determine the net force on the sled by graphical
method using a scale factor 1.0 cm = 4.0 N.

2. You take a three-day hiking. On the first day, you travel 5.0 km heading east. On
the second you enjoyed the scenery so much you forgot to take note how far you
have walked and in what direction. On the third day, after wandering for 8.5 km and
in the direction 37° south of west, you found yourself in the base camp. Determine
your displacement during the second day of your trip. Use the scale 1.0 cm = 2.0

3. A fathor pulls his child on a sled by pulling on a rope over his shoulder with a force
as much as 75 N directed along the rope that makes an angle of 30° with the ground.
The icy ground exerts about 15 N frictional force on the sled. The combined weight
of the sled and the child is about 180 N. Illustrate the concurrent forces on a
Cartosian plane and compute for the resultant force (magnitude and direction) on the
sled.
1. As it passes Grand Bahamas Islands, the eye of the hurricane Katrina is moving in a
direction of 60° north of west at a speed of 50 kph. Three hours later, it shifts due
north where its speed slows to 25 kph. How far from the Grand Bahamas is the eye
of the hurricane 4.5 hrs. after it passes over the island?
