A ball of mass,m, is attached to a string of length,l . It is being swung in a vertical circle with enough speed so that the string remains taut throughout the ball's motion.Assume that the ball travels freely in this vertical circle with negligible loss of total mechanical energy. At the top and bottom of the vertical circle, theball's speeds are vt and vb, and the corresponding tensions in the string are Tt and Tb. Tt and Tb have magnitudes...
A 900 g ball moves in a vertical circle on a 1.07 m -long string. If the speed at the top is 4.10 m/s , then the speed at the bottom will be 7.67 m/s . A) What is the ball's weight? B) What is the tension in the string when the ball is at the top? C) What is the tension in the string when the ball is at the bottom?
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 = 0.178 kg and moves at v = 4.75 m/s. The circular path has a radius of R = 0.91 m 1) What is the magnitude of the tension in the string when the ball is at the bottom of the circle? N Submit + 2) What is the magnitude of the tension in the...
A small ball of mass m is tied to a string and set rotating with negligible friction in a vertical circle of radius R with earth's gravity g acting. (a) What is the speed of the ball at the top of the circle so that the tension in the string vanishes there? (b) Given this, what is the speed of the ball at the bottom of the circle, and (c) what is the tension in the string at the bottom...

The circular path has a radius of R = 0.99 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 ball is...
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 = 0.175 kg and moves at v = 5.22 m/s. The circular path has a radius of R = 1.14 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 ball is...
A child is swinging a 380-g ball at the end of a 69.0-cm-long string in a vertical circle. The string can withstand a tension of 16.0 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 3.90 m/s? (b) What is the maximum speed the ball can have at the bottom of the circle if the string does not break?
The figure below shows a ball of mass m=1.9 kg which is connected to a string of length L=1.5 m and moves in a vertical circle. Only gravity and the tension in the string act on the ball. If the velocity of the ball at point A is v0=10.4 m/s, what is the tension T in the string when the ball reaches the point D? The figure below shows a ball of mass m=1.9 kg which is connected to a...
A spherical mass on the end of a string is spinning in a vertical circle about point P. Which of the forces acting on the mass contribute to the "centripetal force" when the mass is in position A? Select all that apply. The tension in the string. The force of gravity (weight). The force of drag (air resistance). Which of the forces acting on the mass contribute to the "centripetal force" when the mass is in position B, directly to...
The figure below shows a ball of mass m=1.5 kg which is connected to a string of length L=1.4 m and moves in a vertical circle. Only gravity and the tension in the string act on the ball. If the velocity of the ball at point A is v0=8.6 m/s, what is the tension T in the string when the ball reaches the point D? (use figure, but answer the question above.) The figure below shows a ball of mass...
