Answer:

1 m/s west

Explanation:

Impulse = change in momentum

J = m Δv

Taking east to be positive:

300 kg m/s = (75 kg) (v − (-5 m/s))

v = -1 m/s

His new velocity is 1 m/s west.

Magnesium Oxide Reaction

Verizon [17]

Answer:

When magnesium reacts with oxygen, it produces light bright enough to blind you temporarily. Magnesium burns so bright because the reaction releases a lot of heat. As a result of this exothermic reaction, magnesium gives two electrons to oxygen, forming powdery magnesium oxide (MgO).
