Question

A girl is running with a constant velocity of 10 m/s and develops a momentum of
500 kg m/s.The mass of the girl is:
a) 50 kg
b)25 kg
c)100kg
d)40kg

Answer 1

Answer:

option a) 50 kg is correct

Step-by-step explanation:

momentum = 500 kg m/s

velocity = 10 m/s

momentum = mass × velocity

500 = mass × 10

mass = 500/10

mass = 50 kg

Answer 2

for m/s speed of 10 the mass of the girl is 50 kg
