A ball of mass m is fastened to a string. The ball swings in a vertical circle of radius R with the other end of the string held fixed. Neglecting air resistance, what is the difference between the string's tension at the bottom of the circle and at the top of the circle?
A small ball of mass 0.360 kg is attached to a string of length 1.25 m and revolved as shown in the figure below. The breaking tension of the string is 8.00 N. (a) What angle does the string make when the rope is just about to bre...
A ball of mass m is dropped from a height H. When it hits the ground, it rebounds to a height h. If the time of contact with the ground is t, and the average force exerted by the ground on the ball during the collision is F. Which of the following equations is correct accor...
A ball of mass m is suspended from a rope of length L. Now the ball is set into freely swinging circular motion in a vertical plane. If the centripetal acceleration of the ball at the top of the circle is 13g, its centripetal acceleration at the bottom of the circle is closest to ...
kg is tied to a string of length 6.0 m as shown in Figure P6.50.The ball is initially hanging vertically and is given an initial velocity of 5.0 m / s in the horizontal direction. The ball then follows a circular arc...
A ball of mass m falls from a height h to the surface of the Earth.Which one of the following is correct?(assume that h is much smaller than the radius of the Earth)A) If we choose our system to be ball+Earth then the work done on the system is mgh.B) If we choose our s...
