A massless string is tied to a heavy ball whirling in a vertical plane.

1) At what angle is the tension in the string a minimum? a) 0^o, b) 45^o, c) 90^o, d) 180^o, or e) 270^o

2) At what angle is the tension in the string a maximum? a) 0^o, b) 45^o, c) 90^o, d) 180^o, or e) 270^o

3) The tension is independent of the length of the string.

4) At what angle is the string most likely to break? a) 0^o, b) 45^o, c) 90^o, d) 180^o, or e) 270^o

Other parameters being held equal, a change in the mass of the cycling objects above would change:

1) the speed of the plane. True or False

2) the speed of the car. True or False

3) the radius for an earth satellite. True or False

4) the tension in the string. True or False

5) the normal force on the water. True or False

6) the minimum speed required to keep the water in the bucket. True or False

A ball of mass m is tied to a string and is rotating in a vertical...

A ball of mass m is tied to a string and is rotating in a vertical plane. The string is elastic (it stretches), which causes the path to be elongated vertically rather than perfectly circular. At the top of the path, the speed has the minimum value that still allows the ball to complete its circular path. Find: the length of the string when it makes an angle θ with respect to the horizontal. The following quantities are known: Mass...

A small 0.11 kg metal ball is tied to a very light (essentially massless) string that is 0.9 m long. The string is attached to the ceiling so as to form a pendulum. The pendulum is set into motion by releasing it from rest at an angle of 60 ∘ with the vertical. A) What is the speed of the ball when it reaches the bottom of the arc? B)What is the centripetal acceleration of the ball at this point?...

A 1-kg ball is tied to the end of a 2-meter string and revolved in a horizontal plane making a 30o angle with the vertical. (a) What is the ball's speed? (b) If the ball is now revolved so that its speed is 4m/s, what angle does the string need to make with the vertical? (c) If the string can withstand a maximum tension of 10 N, what is the highest speed at which the ball can travel?

A ball is tied to a string and whirled in a horizontal circle at a constant 4 revolutions per second. Categorize the following according to whether they are constant and zero in value, constant and non-zero in value, or non-constant in value: linear speed (scalar) linear velocity (vector) radial (centripetal) acceleration (scalar) radial (centripetal) acceleration (vector) angular speed (scalar) angular velocity (vector) angular acceleration (scalar) angular acceleration (vector)

A 90g ball is tied to a string so that the center its mass hangs 50 cm below the point where the string is tied to a support rod. The ball is pulled aside to a60° angle with vertical and released. As the string approaches vertical, it encounters a peg at a distance x below the support rod. The string then bends around the peg. If the position of the peg is low enough, the ball will move in a...

Two rocks are tied to massless strings and whirled in nearly horizontal circles so that the time to travel around the circle once is the same for both. Once string is three times as long as the other. The tension in the longer string is four times the tension in the shorter one. What is the mass m1 of the rock at the end of the shorter string compared to the mass m2 of the rock at the end of...

A 5.11-kg ball hangs from the top of a vertical pole by a 2.33-m-long string. The ball is struck, causing it to revolve around the pole at a speed of 4.47 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.

A 5.47-kg ball hangs from the top of a vertical pole by a 2.13-m-long string. The ball is struck, causing it to revolve around the pole at a speed of 4.75 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. Answer in degrees. What is the tension of the string? Answer in N

1. A powered model airplane of mass 1.77 kg is tied to a ceiling with string and allowed to fly at speed 0.44 m/s in a circular path of radius 0.44 m while suspended by the string which makes a constant angle with respect to the vertical. (a) What is the angle, in degrees, that the string takes such that the above is true? (b) What is the tension in the string, in N?
