Answer 1

ITS A  5.6m\s

After the collision the system of the ball and dough will travel at a velocity of 5.6 m/s.

Let, m1 = 200 g = 0.2 kg

m2 = 700 g = 0.7 kg

v1 = 25 m/s

The velocity of the system after the collision will be =  

m1

m1 + m2

v1

=  

0.2

0.2 + 0.7

x 25

= 5.5555 m/s = 5/6 m/s
