Part A: Pulley-Rope A pulley-rope mechanism is shown in Figure 1. In order to lift the block $ A $ to a certain elevation, a force $ F $ is required to apply to the end of the cable at point $ B $. The mass of the block $ A $ is 200 kg . The masses of pulley, $ D, C $ and $ E $ and the rope are negligible compared to the mass of block $ A $. The friction of the pulley-rope can be neglected. Figure 1: Pulley-rope mechanism reproduced courtesy the publisher of Hibbeler a) In two ways determine the constant force $ F $ that is required to apply to the rope at point $ B $ in order to lift block $ A $ to reach speed of $ 10 \mathrm{~m} / \mathrm{s} $ at a displacement of 5 m upward starting from rest. 1. Use force and acceleration (Newton 's second law of motion) and kinematics 2. Use work and energy principle $ T_{1}+\sum U_{1 \rightarrow 2}=T_{2} $ b) In two ways determine the velocity and distance of the block $ A $ and point $ B $ in time $ t=4 \mathrm{~s} $ if the applied force at point B is 90 kg . Consider the system is released from rest. 1. Use force and acceleration (Newton's second law of motion) and kinematics. 2. Use impulse and momentum principle: $ m v_{1}=\sum \int_{t_{1}}^{t_{2}} F d t=m v_{2} $
