Consider a horse and a cart. The horse pulls on the cart, and
the cart pulls back on the horse. The two forces are equal and
opposite, so why does the cart move at all? The reason is that the
horse is also exerting a force on the ground, which is external to
the horse-cart system, and the ground exerts a force back on the
horse-cart system causing it to accelerate.
HOW DOES THE HORSE MOVE IF THE FORCE THE HORSE EXERTS ON
GROUND IS EQUAL AND OPPOSITE TO THE FORCE THE GROUND EXERTS ON THE
HORSE, hence cancelling each other out?

You are a medical consultant to a health technology company
evaluating an inexpensive traction system for exerting a
predictable force at the location of a patient’s leg injury. The
device consists of a foot-strap connected to a weight by a rope
that goes over a pulley. You are worried that the force exerted on
the injury will change when the angle of the leg changes. As a
first step in understanding the situation, you decide to model the

A cart of mass m1(pictured) is free to move nearly frictionless
up a ramp at angle θ. A small mass m2 hangs from a string that runs
over a pulley and connects to m1. We will determine the
acceleration of the cart m1 over a known distance x,then plot the
acceleration of m1 as a function of the hanging mass m2.
a) The hanging mass will create a constant pulling force to
accelerate the cart up the ramp. Using Newton’s...

This assignment is about energy. But one of the new things we’ve
just learned about is spring forces, so
there should be a question about them. So some parts of this
question are not about energy. One of the
hard things is deciding whether you should use energy methods or
not in each part. I’ll give you some help
with making this decision by getting you to think about whether
the system is energetically isolated.

In this problem, consider electrostatic forces only. In the
figure, there is a particle of charge +Q at x = 0, and there is a
particle of charge +16Q at x = +4a. You are going to bring in a
third particle, with a charge of −4Q, and place it at an
appropriate spot on the x-axis. Use Q = 60.0 ✕ 10−6C, and a = 40.0
cm. Also, use k = 9.00 ✕ 109 N · m2/C2. (a)First, place...

Most of us know intuitively that in a head-on collision between
a large dump truck and a subcompact car, you are better off being
in the truck than in the car. Why is this? Many people imagine that
the collision force exerted on the car is much greater than that
experienced by the truck. To substantiate this view, they point out
that the car is crushed, whereas the truck in only dented. This
idea of unequal forces, of course, is...

(1) (a) Let’s derive an ideal gas law. Let’s start with a cubic
box with side-length L. Now assume we have a particle traveling
perfectly horizontally towards a single wall. When it collides with
that wall, it will turn around and hit the wall on the other side.
It will continue to bounce back and forth in this way forever. What
is the period of this motion? In other words, how much time does it
take for the particle to...

Case Studies Tasks:
Revisit Jane (One Last Time): Jane was riding
her horse on a warm sunny day (101 degrees Fahrenheit) when
suddenly her horse stopped and reared up in the air. Jane was not
prepared for this and fell hard backwards into the ground. As she
hit the ground Jane's leg was gashed open by a large, sharp boulder
that she fell next to. Jane began to bleed severely. Jane's body
spends the next couple hours physiologically compensating for...
