A 1500kg wrecking ball hangs from a 20m -long cable. The ball is pulled back until the cable makes an angle of 30.0? with the vertical. By how much has the gravitational potential energy of the ball changed?
A-11; In the figure, a 1240-kg wrecking ball is pulled back with a horizontal force of 5480 N before being swung against the side of a building. a) What angle does the wrecking ball make with the vertical when it is pulled back? b) What is the tension in the ball's supporting cable when it is at this angle? 5480N mg
A 4150 kg wrecking ball swings in a horizontal circle motion around a crane, making a 30 ◦ angle from the vertical. If the cable hoisting the ball is 12 m and during the swing the tension in the cable is 55 kN, with what speed is the ball moving? Report the value in m/s rounded to the nearest tenth.
A ball that weighs 0,60 gr hangs from a 1m long string. It's pulled back and let go from a stationary position. At it's lowest point, it hits a 240 gr block on a horizontal table. The ball has a speed of 3,5m/s just before the collision. a) At what height was the ball let go? That is, how far from it's lowest point? b) The block get's a 1,1m/s speed just after the collision. What was the speed of...
A 2.25 kg bowling ball is hung on a 9.50 m long rope. It is then pulled back until the rope makes an angle of 26 degrees with the vertical and released. Find the speed of the ball is at the lowest point. Give your answer in m/s and with 3 significant figures.
A 2.25 kg bowling ball is hung on a 9.50 m long rope. It is then pulled back until the rope makes an angle of 26o with the vertical and released. Find the tension in the rope when the ball is at the lowest point. Give your answer in N and with 3 significant figures.
A 5.61-kg ball hangs from the top of a vertical pole by a 2.43-m-long string. The ball is struck, causing it to revolve around the pole at a speed of 4.17 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. What is the tension of the string?
A contractor is taking a building down with a big 5,500 kg wrecking ball. He uses a crane with a 35m long cable to swing the wrecking ball into the building. How much time does it take to swing the ball into the building from a point the ball is released from the crane?
A 5.59-kg ball hangs from the top of a vertical pole by a 2.49-m-long string. The ball is struck, causing it to revolve around the pole at a speed of 4.33 m/s in a horizontal circle with the string remaining taut. Calculate the angle, between 0
A 5.65-kg ball hangs from the top of a vertical pole by a 2.05-m-long string. The ball is struck, causing it to revolve around the pole at a speed of 4.13 m/s in a horizontal circle with the string remaining taut. Calculate the angle, between 0
