Question

Momentum of car moving with velocity of 72km/hr is 20,000kg m/sec , how much it’s mass ?



It’s numerical please solve it....
It is very important for me

Answer 1

Answer:

As per the question

Momentum (p) = 20,000 kg m/s

velocity (v) = 72 m/s

first we have to convert velocity in its S.I unit

v= 72 × 1000/3600 = 20 m/s

or

v= 72 × 5/18 = 20 m/s

as we know the formula of momentum (p)

momentum = mass × velocity

putting the value

20,000 = mass × 20

mass = 20,000/20

mass = 1000 kg

Answer = 1000 kg
