Chapter 2.2, Problem 4T
At right is a free-body diagram for a cart. All foxes have been drawn to scale. In the Space below, sketch the cart, rope, etc., as they would appear in the laboratory.
What can you say about the motion of the can based on the free-body diagram? For example, could the can be: moving to the left? moving to the right? Station? Explain whether each case is possible and, if so, describe the motion of the cart.

In your solutions, remember to do algebra first to derive equations and plug in values
for numerical solutions at the end.
1. A flatbed truck drives past you on a horizontal, flat road at 100 km/hr. Just when
it passes you, a crate falls off the truck and lands flat on the ground and travels 50
m before coming to a stop. Find the coefficient of kinetic friction between the road
and the crate. Assume that the initial speed of the crate is the same as the truck, 100
km/hr.
In your solution, include appropriate free body diagrams (FBD) for the crate, and
break up the forces acting on the crate into components either on the FBD or in a
table of the components.
In the space to the right of the figure sketch a force diagram for the cart on the table.
Suppose that the hanging mass is 120g. Calculate the net force on the system.
If the mass of the cart was increased but the hanging mass remained the same, how would the acceleration be affected? Explain how you know in terms of net force and system mass.
If masses on the cart were moved from the cart to the hanger, how would the acceleration be affected? Explain how you know in terms of net force and system mass.
For a system mass of 600 g and a hanging weight of .5 N, determine the acceleration of the system.
For every problem, show FBDS and write down Newton's 2nd law in component form. Remember to be
precise in your work: clearly describe what your system of interėst is, pay attention to
vector/component notation, and follow a clear strategy in your work-the layout of your page should
reflect a linear progression of steps and thoughts (please do not jolt down things all over the place!!);
show all details of the calculations that are needed to answer the questions: no guesses of course!
A block with mass M is pushed against a vertical wall with a force of magnitude P and directed at an
angle 0 below the horizontal. The wall and the block experience friction (coefficient of static friction is
Hs). Is it possible to keep the block from sliding downward? And if so, how exactly? Use Newton's 2nd law
to support your answer.
