A steel ball is tied to a long piece of string and the other end of the string is tied to a vertical support forming a pendulum. If the ball (called the pendulum's "bob") is pulled to the side and released, then the ball swings back and forth. What is the direction of the ball's acceleration when it is at the lowest point in its swing? As usual, we ignore the effect of air resistance. in the direction of the...

A ball B is fastened to one end of a 100 cm string and the other is held fixed at point O, the ball whirls in the horizontal circle shown. Find the speed of the ball in its circular path if the string makes an angle of 45 degrees to the vertical. Answer unit in meters
A 99 g ball is tied to the end of a 49 cm long string and...
A 99 g ball is tied to the end of a 49 cm long string and swung clockwise in a vertical circle. The center of the circle is 175 cm above the floor. What is the minimum speed necessary to make it over the top without the string going slack? The ball is being swung at this minimum speed, but then the string is released at the instant the ball is at the top of the loop. How far to...

A small plasticl ball is tied to a very light 26.0 cm string that is attached to the vertical wall of a room. A uniform horizontal electric field of magnitude 36,000 N/C exists in this room. When the ball has been given an excess charge Q = -1.10 uC, you observe that the ball remains suspended, with the string making an angle of 17.4 degrees with the wall. A) What is the direction the electic field E in the room?...

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...

A ball swings in a vertical circle at the end of a rope 1.50 m long. When the ball is 36.9° past the lowest point on its way up, its total acceleration is (-22.5120.2j) m/s2 For that instant, do the following. (a) Sketch a vector diagram showing the components of its acceleration. (Do this on paper. Your instructor may ask you to turn in the sketch.) (b) Determine the magnitude of its radial acceleration m/s2 (c) Determine the speed of...

A child swings a tennis ball attached to a 0.633-m string in a horizontal circle above his head at a rate of 4.50 rev/s. (a) What is the centripetal acceleration of the tennis ball? (b) The child now increases the length of the string to 1.00 m but has to decrease the rate of rotation to 3.50 rev/s. Is the speed of the ball greater now or when the string was shorter? (c) What is the centripetal acceleration of the...
