Question

Wet clay of mass 100 gm hits with the stationary bob of mass 200 gm of a pendulum with a velocity of 20 m/s and sticks to it. Both clay and bob come in motion due to this. Calculate the velocity of the bob after the impact.

Answer 1

Answer:

$pls \: mark \: as \: brainliest \: and \: follow \: me$

Explanation:

see here use conservation of momentum

m1u1+m2u2=m1v1+m2v2

100(20)+200(0)=(100+200)V [as they both stick together and hv equal velocities]

100(20)=300V

20/3=V
