Answer:
The velocity and mass of the target ball are 1.6 m/s and 1.29 kg.
Explanation:
Given that,
Mass of softball = 0.220 kg
Speed = 5.5 m/s
(a). We need to calculate the velocity of the target ball
Using conservation of momentum
....(I)
The velocity approach is equal to the separation of velocity
(b). We need to calculate the mass of the target ball
Now, Put the value of v₂ in equation (I)
Hence, The velocity and mass of the target ball are 1.6 m/s and 1.29 kg.
