Questions
A mass of 10 g moving horizontally with a velocity of strikes a pendulum bob of mass 10 g.
Length of string is 50 cm. The two masses stick together. The maximum height reached by the system
now is (Take, )
detailed solution
Correct option is D
From conservation of linear momentum, velocity of combined mass just after collision will be 50 cms-1, as mass has doubled.Now, H=u22g=(0.5)220 m=1.25 cmTalk to our academic expert!
