- Tarzan hangs from a vine without it breaking. But when he swings on the same vine starting from a high branch, the vine snaps at the bottom of his swing. Explain why this happens.A 21.3-kg child positions himself on an inner-tube which is suspended by a 7.28-m long rope attached to a strong tree limb. The child and tube is drawn back until it makes a 17.4-degree angle with the vertical. The child is released and allowed to swing to and from. Assuming negligible friction, determine the child's speed at his lowest point in the trajectory. PSYWYou have to use the formula (mAvAi) + (mBvBi) = (mAvAf) + (mBvBf) With a stick that has a mass of 0.54kg, a quaranteen cracks a 4.4kg pinata when swinging the stick with a velocity of 4.8m/s. The stick stops after the collision and the pinata swings. What is the swing speed of the cracked pinata right after the collision?
- A 25.00 kg child swings on a single-rope swing at a local park (see image). The swing consists of a single rope of length 3.70 m attached to the seat. When the child sits at rest on the swing without moving, what is the tension in the rope? If the child swings through the lowest point of the swing with a linear speed of 12.00m, what is the tension in the rope at this lowest point? S O 973 N O 1218 N O 245 N O 728 N At which point in the child's swing is the centripetal acceleration the smallest? O At point B, somewhere in between points A and C O At point C, the bottom of the swing when she is moving fastest O At point A, when she momentarily stops moving and changes directionsTwo blocks are connected by a light string that passes over a frictionless pulley as shown in figure below. The system is released from rest when the spring is unstretched. If the hanging block (15 Kg) falls a distance 0.2 m before coming to rest. Find the coefficient of kinetic friction between the block of mass 5 Kg and the surface.OI kinetiC friction betv cen block and surface is lk .35. 10. A block of mass m, = 3 kg is attached to a ball of mass m2 = 5 kg by a rope passing over a light, frictionless pulley as shown in the figure. The coefficient of friction between the block and the surface is µk = 0.4. Starting from rest, the system is released, allowing the ball to fall downward. Calculate the speed of the ball when it has fallen a distance %3D m2 h = 1.5 m. Note that you can use either energetics (conservation of energy) or kinematics (forces) to answer this question. Try both!
- Show that when A+B=C then A2+B2+2ABcos , where is the angle between vectors A and B .A baseball pitcher is employing a ballistic pendulum to determine the speed of his fastball. A 3.3-kg lump of clay is suspended from a cord 2.0 m long. When the pitcher throws his fastball aimed diretly at the clay, the ball suddenly becomes embedded in the clay and the two swing up to a maximum height of 0.080. If the mass of the baseball is 0.21kg, find the speed of the pitched ball. SHOW WORK!Tarzan (83kg) is swinging on a vine that is 0.8 meters long into the waiting arms of Jane below. The net force on Tarzan as he swings is 230N. Unfortunately for him, he misjudges his swing and instead slams into a tree when the vine is completely vertical. His impact with the tree lasts 0.2 seconds, and Jane is not impressed. You can assume he puts a constant force on the tree as he crashes. To make matters worse, after slamming to a stop, he slides down the tree at a constant acceleration of magnitude 0.9m/s 1. what is tarzan’s velocity right before he hits the tree? (Round to the hundredths place and use the rounded value for the rest of the problem) 2. what is the magnitude of the force that the tree puts on Tarzan? 3. What is the magnitude of the frictional force between Tarzan and the tree as he slides down? 4. What is Tarzan’s kinetic energy 0.6 seconds after he begins sliding down the tree? 5. What is Tarzans momentum 0.6 seconds after he begins sliding down the tree?
- Objects with masses m1=15.0kg and m2=6.0 kg are connected by a light string that passes over a frictionless pulley as in the figure below. Find the final speed of the blocks when the block m1 moves down a distance of 1.3 m. Assume that the system starts from rest. (Use conservation of energy)HELP ASAP!!!!!! At the neighborhood playground, your friend sits on a swing and gets pulled back by you tothe highest point that you can reach. When you let go, your friend rides the swing withoutreceiving or providing additional push. Your friend travels along an arc of 14 feet on thefirst swing (back to front). As the swing comes backwards, the length of the arc is .80 of theprevious swing. This continues: each successive arc created by swinging is .80 of theprevious swing.a. Find the length of the arc for the 5th swing (the 5th arc). Round to the thousandthsplace.b. On which swing is the length of the arc first less than 1 foot?c. Find the total distance your friend travels in all of the swings up to and including theswing in answer to letter b.Escaping from a tomb raid gone wrong, Lara Croft (m = 60.0 kg) swings across an alligator-ingested river from a 9.45-m-long vine. If her speed at the bottom of the swing is 5.30 m/s and she makes it safely across the river, what is the minimum breaking strength of the vine?
