The last choice is your answer, I just did it.
Answer:
m = 47.5 Kg
Explanation:
given,
speed of skater toward north, v = 0.8 m/s
momentum of the skater in north, P = 38 Kg.m/s
mass of the skater = ?
we now,
Momentum is equal to the product of mass and velocity
P = m x v
38 = m x 0.8
m = 47.5 Kg
hence, mass of the skater is equal to 47.5 Kg.
