A boxer hits a punching bag and gives it a change in momentum of 12 kg multiplied by m divided by s over 7.0ms what is the magnitude of the net force on the punching bag

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

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
