Explanation & Answer

HiPlease check the attached file, thanks. James

1 The spring constant is
k = mg/x = 3*9.8/0.15 = 196 N/m
For 4kg block, use conservation of mechanical energy, we have
Mgymax = ½k*ymax^2

Ymax = 2Mg/k = 2*4*9.8/196 = 0.40 m = 40 cm
2. Using conservation of mechanical energy, we have
½ mV^2 =1...
