Answer:

1714N

Explanation:

The change in momentum of an object is the product of mass and the change in velocity

The magnitude of the netforce can be calculated using 12kg/7.0ms

But we can convert 7ms to "s" = 7× 10^-3s

F= Force = 12/7×10^-3= 1714N

Hence, the magnitude of the net force on the punching bag is 1714N
