A student is swinging a ball on a string overhead in a horizontal plane. The string initially has length ?0 and the ball is moving with an initial speed ?0. The student decides to see how fast they can spin the ball, so they begin moving it faster and faster with a constant tangential acceleration ?? . However, they know that the string is close to breaking, so they decide to keep letting the string get longer and longer in...

1- A 300 ? mass is attached to
a solid 40 ?? long string the other end of which is secured to the
ceiling. The mass is given an initial speed which makes it swing
around a circular path in the horizontal plane without changing its
speed and without changing its height. The object completes 2
revolutions in 2 seconds.
A) What is the magnitude of the angular velocity of this
circular motion? B) Find the tension in the string....

Question 3 The figure shows a conical pendulum, in which the bob (the small object at the lower end of the cord) moves in a horizontal circle at constant speed. (The cord sweeps out a cone as the bob rotates.) The bob has a mass of 0.035 kg, the string has length L = 1.1 m and negligible mass, and the bob follows a circular path of circumference 0.76 m. What are (a) the tension in the string and (b)...

In the apparatus shown above, one end of a string of length L is
attached to a block of mass M and the other end is connected to the
axle of a motor that rotates, causing the block to move in a circle
of radius R at a constant speed vT such that the string makes an
angle θ with the vertical. A student wants to use the apparatus to
make measurements and create a graph that can be used...

A light string can support a stationary hanging load of 25.4 kg before breaking. An object of mass m = 3.23 kg attached to the string rotates on a frictionless, horizontal table in a circle of radius r = 0.795 m, and the other end of the string is held fixed as in the figure below. What range of speeds can the object have before the string breaks? OSVS Your response differs from the correct answer by more than 10%....

A 0.45 kg object rests on a frictionless horizontal surface, where it is attached to a massless spring whose k-value equals 24.0 N/m. Let x be the displacement, where x = o is the equilibrium position and x > 0 when the spring is stretched. The object is pushed, and the spring compressed, until хі =-4.00 cm. It then is released from rest and undergoes simple harmonic motion. (a) What is the object's maximum speed (in m/s) after it is...
