5 m/s2 in a

at will be the
19. A ball of mass 100 g and another ball of 120 g moves
towards each other with speeds 6 m/s and 5 m/s
respectively. If they stick to each other after
colliding, What would be the velocity of the
combined mass after the collision?
50 ke is moving on a straight track
for 4 s. Find​

Answer 1

NANBA..

we know that it is a perfect inelastic collison,the velocity after colliding is

v=m1u1+m2 u2/m1+m2

here m1=100g u1=6m/s

m2=120g u2=-5m/s(since both are moving in opposite direction)

v=100(6)+120(-5)/100+120

=600-600/220

=0..

Hooe usefull...
