Chapter 03, Problem 23
As preparation for this problem, review Conceptual Example 10. The drawing shows two planes each dropping an empty fuel tank. At the moment of release each plane has the same speed of 145 m/s, and each tank is at the same height of 3.18 km above the ground. Although the speeds are the same, the velocities are different at the instant of release, because one plane is flying at an angle of 15.0° above the horizontal and the other is flying at an angle of 15.0° below the horizontal. Find the (a) magnitude and (b) direction of the velocity with which the fuel tank hits the ground if it is from plane A. Find the (c) magnitude and (d) direction of the velocity with which the fuel tank hits the ground if it is from plane B. In each part, give the direction as a positive angle with respect to the horizontal.

As preparation for this problem, review Conceptual Example 9.
From the top of a cliff overlooking a lake, a person throws two
stones, as shown in the drawing. The cliff is 35.0 m high. The two
stones described have identical initial speeds of
v0 = 17.6 m/s and are thrown at an angle
θ = 31.3 °, one below the horizontal and one above the
horizontal. What is the distance between the points where the
stones strike the water? Neglect...

In preparation for this problem, review Conceptual Example 7. A
space traveler whose mass is 101 kg leaves earth. What are his (a)
weight and (b) mass on earth and (c) weight and (d) mass in
interplanetary space where there are no nearby planetary
objects?

Chapter 05, Problem 30 (Vector Drawing)
The drawing shows a baggage carousel at an airport. Your
suitcase has not slid all the way down the slope and is going
around at a constant speed on a circle (r = 11.0 m) as the
carousel turns. The coefficient of static friction between the
suitcase and the carousel is 0.760, and the angle θ in the
drawing is 35.0°. (a) Draw the free-body diagram
showing the forces that act on the suitcase....

1. Before working this problem, review Conceptual Example 14. A
pellet gun is fired straight downward from the edge of a cliff that
is 12 m above the ground. The pellet strikes the ground with a
speed of 28 m/s. How far above the cliff edge would the pellet have
gone had the gun been fired straight upward?

Chapter 6.1 review questions, #23 part B. In order to find the
probability of a fourth or fifth live birth, I have to multiple the
probability of a fourth birth and the probability of a fifth birth.
This would be 0.096 x 0.047. My calculator is saying the answer is
0.004512. However, Chegg textbook solutions and the book says the
answer is 0.143, which would be the two probabilities being added
together. I'm not sure which is wrong; is the...

This problem is similar in spirit to Example 12 (in the chapter)
and Problem 15 (at the end of the chapter). I'd strongly suggest
that you master those two problems before attempting this problem.
Make sure that you draw a high quality, detailed timeline – similar
in quality to those in Example 12 and Problem 15. Assume that you

Chapter 03, Problem 15
A skateboarder shoots off a ramp with a velocity of 6.0 m/s,
directed at an angle of 52° above the horizontal. The end of the
ramp is 1.4 m above the ground. Let the x axis be parallel
to the ground, the +y direction be vertically upward, and
take as the origin the point on the ground directly below the top
of the ramp. (a) How high above the ground is the
highest point that the...

The IASB and FASB are pursuing a single, converged conceptual
framework. The United States has a good start with SFAC No. 8. What
additional changes should FASB make to further improve its
conceptual framework?
