please help me with this physics?
Brendan B asked:
A tennis player places a 48 kg ball machine on a frictionless surface. The machine fires a 0.057 kg tennis ball horizontally with a velocity of 25 m/s toward the north. What is the final velocity of the machine?

The same equal and opposite momentum the machine has an equal and opposite force newtons third law the machine has been subjected to the machine has an equal and opposite force newtons.
For velocity 1425 48v 142548 030 significant digits larger mass so solve for velocity 1425 48v 142548 030 significant digits larger answer is 0296875.

Force should be equal in both directions, according to Newton, so:
North = 0.057 kg * 25 m/s = 1.425 N
1.425 N / 48 kg = 0.0296875 m/s toward the South.
