Two hockey players are about to collide on the ice, so the total momentum of the system when they collide is 23 kg m/s. Hence, option B is correct.
What is momentum?
The result of a particle's mass and velocity is momentum. It has both magnitude and direction because momentum is a vector quantity. According to Isaac Newton's second law of motion, the force pushing a particle has an equal and opposite effect on the temporal rate at which its momentum changes.
[tex]Momentum (p)= Mass(m)*Velocity(v)[/tex]
The given values according to the question is :
p₁ = p₂
(m × v)₁+ (m × v)₂ = (m × v)₁' + (m × v)₂'
(70 kg × 1.4 m/s) + (75 kg) × (-1.0 m/s) = p₂
(98 kg m/s) + (- 75 kg m/s) = 23 kg m/s North
Therefore, the total momentum after collision is 23 kg m/s North.
