A) Zero
B) 5cm
C) 2.5cm
D) 1.25cm
Correct Answer: D
Solution :
[d] Apply momentum conservation \[10\times 100=(10+10)V\] V = 50 cm/sec Kinetic energy so acquired is converted into gravitational potential energy \[\frac{1}{2}\times 20{{(50)}^{2}}=20\times 1000\times h\] \[h=1.25cm\]You need to login to perform this action.
