Answer:
The velocity of the bowling should be 2 m/s in order to an have same momentum as that of basket ball.
Step-by-step explanation:
Momentum is defined as motion possessed by the moving object.it is calculated by multiplying mass of the object with its velocity.

Mass of basket ball = m = 1 kg
Velocity of the basket ball,v = 12 m/s
Momentum of the basket ball = p
p = 1 kg × 12 m/s = 12 kg m/s
Mass of bowling ball = m' = 6 kg
Velocity of the bowling ball = v'
Momentum of the bowling ball = Momentum of the basket ball = p
p = m' × v'
12 kg m/s = 6 kg × v'
v ' =

The velocity of the bowling should be 2 m/s in order to an have same momentum as that of basket ball.
