_'_-__-...-____ 013 10.0 points An Atwood machine is constructed using two wheels (with the masses concentrated at the rims). The left wheel has a mass of 2.4 kg and radius 236 cm. The right wheel has a mass of 2.4 kg and radius 32.92 cm. The hanging mass on the left is 1.94 kg and on the right 1.26 kg. 6! 9 ' m .4 What is the acceleration of the hanging mass on the left? Use down as the posi- Itive direction. The acceleration of gravity is 9.8 m/s2 . Answer in units of III/82. 014 10.0 points A horizontal 809 N merrygoround of radius 1.23 In is started from rest by a constant horizontal force of 74.2 N applied tangentially to the merryugoround. Find the kinetic energy of the merry-go- round after 2.46 s. The acceleration of gravity is 9.8 rn/s2 . Assume the merrygoround is a solid cylinder. Answer in units of J. )I'
