Question

P is the momentum of a body of mass m moving with velocity V. What is the momentum of a body of mass m/2 moving with a velocity 2V

Answer 1

mass is2 and velocity is2 so total answers is 4 because mass multiple by velocity

Answer 2

P= √2mk.e
K.e = 1÷2 mv2
K.e = 1÷2 m (2v)2
K.e = 4 k.e

P= √ 2m k.e
P= √2(m÷2) (4 k. E)
P = √2p

Mean answer us √2 time of p
