```							m = 5kg, x = 10cm = 0.1m,
v = 2m/sec, h =?
G = 10m/sec2
S0, k = x mg
= 0.1 50 = 500 N/m
Total energy just after the blow E = ½ mv2 + ½ kx2 …(i)
Total energy a a height h = ½ k (h – x)2 + mgh …(ii)
½ mv2 + ½ kx2 = ½ k (h – x)2 + mgh
On, solving we can get, H = 0.2 m = 20 cm

```							Q-41.
m = 5kg, x = 10cm = 0.1m, v = 2m/sec,
h =? G = 10m/sec2
S0, k =mg/x  =50/.1 = 500
Total energy just after the blow E = ½ mv2 + ½ kx2 …(i)
Total energy a a height h = ½ k (h – x)2 + mgh …(ii)
½ mv2 + ½ kx2 = ½ k (h – x)2 + mgh
