Question

a boy of mass of 40 kg runs at 6.0 m/s what is his momentum

Answer 1

Given :

• Mass of boy, m = 40 kg

• Velocity, v = 6.0 m/s or 6 m/s

To find :

• Momentum of boy, p

According to the question,

We know that,

Momentum is product of mass and velocity.

So,

➞ Momentum = Mass × Velocity

Or,

➞ p = m × v

➞ Substituting the values,

➞ p = 40 kg × 6 m/s

➞ p = 240 kg m/s

So,the momentum of boy is 240 kg m/s.

_____________________________

More details :-

• SI unit of momentum is kg m/ s.

• Momentum can be denoted as 'p'.

• Momentum is vector quantity.

Answer 2

Answer:

$\huge \bf \: Given$

• Mass of the boy (M) = 40 kg
• Velocity (V) = 6 m/s

$\huge \bf \: To \: find$

Mounmentum (P)

$\huge \bf Answer$

Mounmentum is defined as product of mass and velocity.

$\huge \fbox {P\: = MV}$

Here,

P - Mounmentum

M - Mass

V - Velocity

$\tt \: p \: = 40 \times 6$

$\tt \: p \: = 240$

Therefore Mounmentum of boy is 240 kg m/s.
