Question

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?

Answer #1

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 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...

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 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 wrecking ball swings at the end of a 10.3-m cable on a
vertical circular arc. The crane operator manages to give the ball
a speed of 10.9 m/s as the ball passes through the lowest point of
its swing and then gives the ball no further assistance. Friction
and air resistance are negligible. What speed vf does the ball have
when the cable makes an angle of 28.5 ° with respect to the
vertical?

A wrecking ball swings at the end of a 14.7-m cable on a
vertical circular arc. The crane operator manages to give the ball
a speed of 10.7 m/s as the ball passes through the lowest point of
its swing and then gives the ball no further assistance. Friction
and air resistance are negligible. What speed vf does the ball have
when the cable makes an angle of 10.3 ° with respect to the
vertical?

An athlete swings a 3.10-kg ball horizontally on the end of a
rope. The ball moves in a circle of radius 0.660 m at an angular
speed of 0.520 rev/s. (a) What is the tangential speed of the ball?
m/s (b) What is its centripetal acceleration? m/s2 (c) If the
maximum tension the rope can withstand before breaking is 136 N,
what is the maximum tangential speed the ball can have? m/s

An athlete swings a 4.70-kg ball horizontally on the end of a
rope. The ball moves in a circle of radius 0.770 m at an angular
speed of 0.670 rev/s.
(a)
What is the tangential speed of the ball?
m/s
(b)
What is its centripetal acceleration?
m/s2
(c)
If the maximum tension the rope can withstand before breaking is
138 N, what is the maximum tangential speed the ball can have?
m/s

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?

An athlete swings a 6.50-kg ball horizontally on the end of a
rope. The ball moves in a circle of radius 0.830 m at an angular
speed of 0.570 rev/s.
(a) What is the tangential speed of the ball? _____m/s
(b) What is its centripetal acceleration?
_____m/s2
(c) If the maximum tension the rope can withstand before
breaking is 96 N, what is the maximum tangential speed the ball can
have? _____m/s
