Consider a conical pendulum with a bob of mass m = 28.0 kg on a
string of length L = 7.00 m that makes an angle of θ = 4.00° with
the vertical. a) Draw the direction of the acceleration of the ball
b) What force(s) cause this acceleration? c) Determine the
centripetal acceleration of the bob. d) Determine the speed of the
ball.
A pendulum consists of a ball of mass 3.0 kg on a string of
length 4.0 m. The ball is pulled back untilits center has risen to
a height of 0.80 m. The ball is released such that it strikes a 1.0
kg block at thebottom of its swing. The block comes to a rest after
traveling 2.0 m across a surface withμk= 0.15.What is the speed of
the ball right after the collision? Is the collision elastic?
A pendulum consists of a stone with mass m swinging on a string
of length L and negligible mass. The stone has a speed of
v0 when it passes its lowest point. (a) Write an
expression for the speed of the stone when the string is at some
angle theta with the vertical. (b) What is the greatest angle with
the vertical that the string will reach during the stone's motion?
(c) If the potential energy of the pendulum-Earth system...
A simple pendulum may
be described ideally as a point mass suspended by a massless string
from some point about which it is allowed to swing back and forth
in a place. A simple pendulum can be approximated by a small metal
sphere which has a small radius and a large mass when compared
relatively to the length and mass of the light string from which it
is suspended. If a pendulum is set in motion so that is swings...
A meter stick (?= 1.00 m, ?= 100 g) is made into a physical
pendulum by drilling a small hole at a distance ?from the center of
mass to become the pivot point. Find the distance ?, if the
pendulum is to have a period of ?= 3.00 s.
A.3.79 cm
B.14.6 cm
C.20.4 cm
D.40.9 cm
E.It cannot be done.
Consider a pendulum consisting of a mass m in a gravitational
field, with the (massless) pendulum arm being a spring of spring
constant k and “resting length” b. The pendulum is confined to move
in a plane as usual. Write the Lagrangian and find the equations of
motion.
1) A meter stick is placed in a support stand and balanced at its center of gravity. A 50 gram mass is placed at the 25.00 cm mark. An unknown mass is placed on the other side of the meter stick and moved until the entire system is balanced. If the unknown mass is placed at the 75.00 cm mark, then what is the value of the unknown mass? Ignore the mass of the knife-edge clamps and assume that...
How does the adding spin to the string(we twisted the string) of
the sipmle pendulum affect to its period (T). Show some equations
and work to prove if there's any affect to the period of
pendulum.
The center of gravity of the meter stick is 49 cm. mass of meter
stick 50 g . mass of hanger #1 =5 g. mass of hanger #2 = 5 g.
1.Place the fulcrum at 51 cm. Attach a 200 g mass, plus hanger
#1, at 17 cm on the meter stick and calculate where to attach a 200
g mass, plus hanger #2, to balance it.
2.Balance the stick with the fulcrum at its center of gravity.
Attach a...
There are two correct answers for this question:
A simple pendulum and a spring-mass pendulum both have identical
frequencies. Which changes will result in the spring-mass system
having twice the period of the pendulum?
a) Quadruple the mass of the simple pendulum
b) Replace the spring with one half the spring constant and
double the mass
c) Make the string on the pendulum four times smaller and make
the pendulum 4 times more massives
d) Double the mass in the...
