A 34 kg cheetah waits to stalk its prey in the desert, tentatively watching a gazelle.
A. Once he decides to attack, how much net force must the cheetah apply to itself to reach 29 m/s directly west in 3.1 seconds?
b. Shortly after reaching top speed, the cheetah must navigate around a tree. If the cheetah is now moving 23.5 m/s north, what is its change in momentum?
c. Realizing the gazelle he thought he saw was simply a mirage, the cheetah decides to change his course and go hunting elsewhere. Not in much of a hurry the cheetah now moves 23 degrees west of north at 13 m/s. what is the cheetah's new change in momentum?
Solutions
Expert Solution
------------------------------ Solution of part A ---------------------------------
mass of cheeta = 34 Kg
final velocity = 29 m/s
time taken = 3.1 s
and
So force required by cheeta is 318.065 N
------------------------------ Solution of part B ---------------------------------
change in momentum = fnal momentum - initial momentum
------------------------------ Solution of part C ---------------------------------
change in momentum = fnal momentum - initial momentum

A cheetah spots a Thomson's gazelle, its preferred prey, and
leaps into action, quickly accelerating to its top speed of 30
m/sm/s, the highest of any land animal. However, a cheetah can
maintain this extreme speed for only 15 ss before having to let up.
The cheetah is 310 mm from the gazelle as it reaches top speed, and
the gazelle sees the cheetah at just this instant. With negligible
reaction time, the gazelle heads directly away from the cheetah,...

Two friends Colby [mass mC = 34 kg] and Charlie [mass mCh = 42
kg] are avid swimmers. Colby is a master swimmer, while Charlie
only swims recreationally. They both start on one side of pool (x =
0) at the same time (t = 0). The pool is separated into lanes along
the “long course” so that the other end is at x = 50 m. Colby swims
2,500 m in 55 minutes; we assume that Colby and Charlie...

GAZELLE … OR TURTLE?
Summit Software, Inc., recently celebrated its fifth year of
business. Jim Mueller, the proprietor, started the software
manufacturing and distribution company when he was still working as
a professor at the local college, but now he enjoys being in the
fast-paced technology industry. Growth and expansion were easy for
Jim, thanks to his knowledge, his contacts, and the pool of readily
available workers from which to choose. The company that originated
in his...

What is the acceleration of the 62 kg block if θ =
34, μ s = 0.4, and μ k =
.3? Round your answer to three significant figures.
If the block starts from rest at the position L = 25 m,

A dockworker loading crates on a ship finds that a 34-kg crate,
initially at rest on a horizontal surface, requires a 73-N
horizontal force to set it in motion. However, after the crate is
in motion, a horizontal force of 50 N is required to keep it moving
with a constant speed. Find the coefficients of static and kinetic
friction between crate and floor

. a) The solar installation generates electric power from
sunlight and incurs operating costs for cleaning the solar modules
(sometimes called solar panels) and replacing solar modules that
have failed. The annual revenue from the electric power is variable
due to variable cloudiness and solar module failure and has a mean

Sarah Tynan's image of a hen harrier taking a Range Rover as its
prey is clearly a piece of wishful thinking--or, as Jeremy Deller
called the exhibition in which it served as the focal point,
English Magic. What is "magical" about it? Are you
sympathetic with Deller's point of view? In the United States,
wolves are protected by the Endangered Species Act, but wolves
often come into conflict with ranchers who claim that they kill
their livestock. If you could...

A kestrel dives from a stationary hover, 20 m above the ground,
to catch its prey, typically mice, on the ground. (a) If the
kestrel’s acceleration toward the ground is due solely to free
fall, calculate how long it takes to reach the ground. (3 points)
(b) A field mouse can run at a top speed of 10 km/h, which it
achieves starting from rest in 1 s. Assuming that the only way for
the mouse to survive the kestrels...
