Consider the Atwood system shown below The pulleys are ideal the ropes are light and the inclines have negligible friction The spring has a stiffness of 50 N m and when the system is released from rest is initially stretched by 0 4 m Mass A is 9 1 kg and mass B is 45 0 kg No the incline angles are such that cos 0 12 13 sin 0 5 13 for the left incline and cos OR 3 5 sin OR 4 5 for the right incline A Take g 10 0 m s When block B slides 2 4 m down the incline determine a 2 the exact integer change in block A s gravitational potential energy b 2 the exact integer change in block B s gravitational potential energy c 2 the exact integer change the system s spring potential energy d 2 the speed of block A accurate to three sig digs m s fixed G B
