Newton's second law of motion:
Force = (mass) x (acceleration)
Put in the numbers you know: Force = (1.04 kg) x (987 m/s²)
Do the arithmetic: Force = 1,026.5 newtons
What was confusing about that ?
I agree that these numbers are ridiculous . . . a force of about 230 pounds,
which no hockey player can muster, even with the mechanical advantage
of his stick, to give a little hockey puck an acceleration of about 100 'G's,
which would totally annihilate the poor puck. But that's how it works out
with the numbers given in the question.
