A mass of 10 gm moving with a velocity of 100 cm/s strikes a pendulum bob of mass 10 gm. The two masses stick together. The maximum height reached by the system now is 
Text Solution
Verified by ExpertsThe correct answer is:
D
Initially mass 10 gm moves with velocity 100 cm/s
∴ ∴ Initial momentum = 10 × 100 = 
After collision system moves with velocity 
then
Final momentum = 
By applying the conservation of momentum
10000 = 
⇒ ⇒ 
If system rises upto height h then
