- An inventive child named Nick wants to reach an apple in a tree without climbing the tree. Sitting in a chair connected to a rope that passes over a frictionless pulley (see figure below), Nick pulls on the loose enc of the rope with such a force that the spring scale reads 310 N. Nick's true weight is 310 N, and the chair weighs 160 N. Nick's feet are not touching the ground. Use g=9.8 m/s². (b) Find Nick's acceleration, using upward as positive. m/s² (c) Find the magnitude of the force Nick exerts on the chair. (d*) Instead Nick hands the rope with the scale to his friend Barney, who stands on the ground. Barney pulls on the rope so that the spring scale again reads 310 N. What is Nick's acceleration now, again using upward as positive.It has been determined that a force over 200 N can injure the hand. What is the shortest period of time it will take to stop a 2 kg object traveling at 75 m/s if the hand is to be protected?A conical pendulum has length l and the angle made by the string with vertical is e = 35° . The mass of the object is m=124 g. If the speed of the object is v=3.9m/s find the length of the string. Take g=10Om/s2. Round your answer to one decimal place.
