Question

Review Part A The two masses in the Atwood's machine shown in the figure have an initial speed of 0.19 m/s, and my is moving upward. (Figure 1) How high does my rise above its initial position before momentarily coming to rest, given that m 31 kg and m = 42 kg? Express your answer using three significant figures. Figure < 1 of 1 V AXD O ?

Answer 1

solution & Let us take acceleration of system be a and Tension in the string =T then using equation for 4.29 - Tz | 4.29 -O T-3.19= 3.19 @ a = (4-2-3-1)g 4.27311 a=1.48 m]s to now velocity is opposite acceleration so Zuz znach n = (019) 241.48 h=0.012 mely h=[122 cm
