A ball of mass m-3.50 kg is attached to a horizontal massless cord of length l- 2.00 m, and the other end is fixed, as shown. The ball is released from rest from the highest point, A. Peg a. b. What is the speed of the ball when it reaches its lowest point, B? How much work is done by gravity as the ball moves from point A to point B, its lowest point? c. How much work is done...
A ball is attached to a horizontal cord of length L=1.01 m whose
other end is fixed, as shown.
If the ball is released, what will be its speed at the lowest point
of its path?
Correct, computer gets: 4.45 m/s
B) A peg is located a distance h directly below the point of
attachment of the cord. If h = 0.740L, what will be the speed of
the ball when it reaches the top of its circular path about...
A 1.9-kg ball is attached to the end of a 2.6-m string to form a pendulum. This pendulum is released from rest with a string horizontal. At the lowest point in its swing when it is moving horizontally, the ball collides elastically with a 2.5-kg block initially at rest on a horizontal frictionless surface. What is the speed of the block just after the collision? Show all the important physics steps.
A ball with mass m= 0.98 kg, is attached to a horizontal cord of length l = 59 cm whose other end is fixed. A peg is located a distance h = 12 cm directly below the point of attachment of the cord. After the ball is released, what will be the tension (in N) in the cord when it just starts its circular path about the peg?
Conservation problem
A ball is attached to a horizontal cord of length L whose other end is fixed (see picture), (a) If the ball is released, what will be its speed at the lowest point of its path? (b) A peg is located a distance h directly below the point of attachment of the cord. If h = 0.7 L, what will be the speed of the ball when it reaches the top of it circular path about the peg?...
A 1.0 kg object is attached to one end of a 1.25 m long string. The other end of the string is fixed. The object is released from rest when the string is horizontal falls to a vertical 90-degree angle. What is the speed of the object as the lowest point along the path (when the string is vertical)? What is the value of the tension in the string at the lowest point? What is the work done by the...
A 1 kg solid ball is attached to the end of a 3 m string to form a pendulum. This pendulum is released from rest from a horizontal position. At the lowest point in it's swing the ball collides with a cylinder of radius 20 cm and 2 kg mass that is at rest on a horizontal surface. (a) (20 points) What is the linear velocity of the cylinder right after the collision with the pendulum. (b) (10 points) Considering...
2. A small box of mass m is kept on a fixed, smooth sphere of radius R at a position where the radius through the box makes an angle of 30° with the vertical. The box is released from the position. (a) What is the force exerted by the sphere on the box just after the release? (b) Find the distance travelled by the box before it leaves contact with the sphere. 3. A particle is suspended from a fixed...
A boy is holding the free end of a string, which is attached to a ball on the other end. He rotates the ball on a horizontal table with a constant speed of 2.27 m/s. If the mass of the ball is 0.437 kg, and the length of the string is 0.169 m, what is the tension in the string?
A thin stick of mass 0.5 kg and length
L = 0.8 m
is attached to the rim of a metal disk of mass
M = 5.0 kg
and radius
R = 0.4 m.
The stick is free to rotate around a horizontal axis through its
other end (see the following figure).
(a)
If the combination is released with the stick horizontal, what
is the speed (in m/s) of the center of the disk when the stick is
vertical?
m/s...
