Question

Determine the momentum of a 12-kg dog that is running at 5 m/s.

Answer 1

Given :-

• Mass of a dog (m) = 12 kg
• Velocity (v) = 5 m/s

To Find :-

• Momentum of a dog.

Solution :-

As we know that,

p = m × v

Here,

• p = Momentum
• m = Mass
• v = Velocity

Units,

• p = kg.m/s
• m = kg
• v = velocity

_________________________

Information about momentum,

• Common symbols :- p
• SI unit :- kg⋅m/s
• Other units :- slug⋅ft/s
• Dimension MLT-¹

______________________________

[ Now, substitute the values in momentum formula ]

↪ p = 12 × 5

↪ p = 60 kg.m/s

Therefore,

The momentum of a dog is 60 kg.m/s .

Answer 2

Momentum = mass* velocity
= 12*5= 60 kgm/sec
