Answer:
p = mv, where p is momentum, m is mass, and v is velocity.
a. ) m = 12kg v = 14m/s
Momentum (p) = mv
= 12kg × 14m/s
= 168kg•m/s
b.) momentum (p) = 35 kg•m/s
velocity = 3m/s
p = mv
make m the subject
divide both sides by v
we get
m = p/v
Therefore m is
m = 35 kg•m/s / 3m/s
m = 11.67kg
Therefore the mass of the object is 11.67kg
Hope this helps
Changes in the dip of the earth's magnetic field correspond to changes in latitude. Displacing migrating birds to areas of smaller dip angles (= lower magnetic latitudes) results in predeterminable shifts in the birds migratory direction .
