Answer 1

$\huge\star{\mathfrak{\underline{\underline{\red{Answer}}}}}$

_______________________________________

Speed of cart + speed of man =10m/s__________(1)

We know That

Initial Momentum(pi) = Final Momentum(pf)

So,

$\star{\mathscr{\underline{\underline{\orange{Pf=m1v1+m2v2}}}}}$

0=60u-120v

120v=60u

2v=u____________(2)

From 1 and 2

2v+v=10

v=10/3 m/s
