Question

A ball with a mass of 1.50 kg is attached to the end of a string that is 0.400 m in length. You swing the ball so that it swings in a vertical circle, traveling at a speed of 4.80 m/s at the top of the circle. (a) Draw the free-body diagram of the ball. Make sure you label all your vectors and clearly indicate their direction. (b) What is the tension in the string when the ball is at the topmost point of the circle?

Answer #1

**Concept** - use Newton’s law of motion for the
motion of the ball at the top of the circle to find the required
value of tension as shown below***************************************************************************************************

**This concludes the answers. If there is any mistake or
omission, let me know immediately and I will fix
it....**

A ball of mass of 10 kg is attached to one end of a string. The
other end of the string is attached to the ceiling. The ball swings
and undergoes 5 full oscillations in 18.00 seconds.
(a) Calculate the length of the string.
_____ m
(b) If the amplitude of motion of the pendulum is 15,
calculate the total energy of the oscillator.
_____ J

A ball swings in a vertical circle at a constant speed at the
end of a 1.5-m-long string. When the ball is at the top of the
circle, the tension is 10N, at the bottom the tension is 50N.
a) What is the mass of the ball?
b) What is the speed of the ball?

A 3970 kg demolition ball swings at the end of a 34.4 m cable on
the arc of a vertical circle. At the lowest point of the swing, the
ball is moving at a speed of 2.08 m/s. Determine the tension in the
cable.

A 0.0410- kg ball swings on the end of a 1.270- m-long string.
On one swing the tension in the string is 1.177 N at the lowest
point. By the second swing the ball has lost 9.3 percent of its
energy. What is the ball's speed at the lowest point on the second
swing?

1. For a stationary ball of mass m = 0.200 kg hanging from a
massless string, draw arrows (click on the “Shapes” tab) showing
the forces acting on the ball (lengths can be arbitrary, but get
the relative lengths of each force roughly correct). For this case
of zero acceleration, use Newton’s 2nd law to find the
magnitude of the tension force in the string, in units of Newtons.
Since we will be considering motion in the horizontal xy plane,...

A 50.0 g ball swings in a vertical circle at the end of a string
of length 39.8 cm. If the speed of the ball at the bottom is 5.11
m/s, what is the speed of the ball at the top?
B) Find the work done by gravity on the ball as it goes from
bottom to top.

A 0.37 kg ball is attached to a 0.71 m long string. The other
end of the string is then attached to the ceiling in order to
create a pendulum. It is then drawn back such that the string makes
an angle of 50 degrees relative to the ceiling and then released
from rest. How fast is the pendulum traveling when the string makes
an angle of 20 degrees relative to the vertical

A child is swinging a 330-g ball at the end of a 69.0-cm-long
string in a vertical circle. The string can withstand a tension of
15.0 N before breaking.
(a) What is the tension in the string when the ball is at the
top of the circle if its speed at that point is 3.50 m/s?
_________ N
(b) What is the maximum speed the ball can have at the bottom of
the circle if the string does not break?...

A string of 4.00 cm long hangs from a ceiling with a ball
attached to it. When the ball an the string are placed in a
horizontal position and released from rest, the ball swings along
an arc. How fast ( in m/s) is the ball going at the lowest point in
its swing?

A ball of mass m is attached to a string. It is spun around at a
distance r at 2 m/s, where the tension in the string is measured to
be 10 N. If the ball is then spun around at 8 m/s, what is the new
tension in the spring?
