Question

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?

_________ m/s

Answer #1

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.

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

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

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 tennis ball connected to a string is spun around in a
vertical, circular path at a uniform speed. The ball has a mass m =
0.154 kg and moves at v = 5.16 m/s. The circular path has a radius
of R = 1.01 m
1) What is the magnitude of the tension in the string when the
ball is at the bottom of the circle?
2) What is the magnitude of the tension in the string when the...

the figure shows a 3.0 kg ball tied to the end of a 50 cm long
string being swung in a circle in a vertical plane at constant
speed. The center of the circle is h = 230 cm above the floor. The
ball is swung at the minimum speed necessary to make it over the
top without the string going slack. If the string is released at
the instant the ball is at the top of the loop, how...

A 5.39-kg ball hangs from the top of a vertical pole by a
2.45-m-long string. The ball is struck, causing it to revolve
around the pole at a speed of 4.79 m/s in a horizontal circle with
the string remaining taut. Calculate the angle, between 0° and 90°,
that the string makes with the pole. Take g = 9.81 m/s2.
What is the tension of the string?

A 0.180-kg ball on the end of a------ meter long cord (neglect
the mass of the cord) is swung in a vertical circle. The ball
passes the top point of the arc at velocity
v2 = 3.88-m/s. The tension at the
bottom is FT2 is------- Newtons
