Question

Determine the mass of an object if it's moving at 5 m/s and has a momentum of 50 kg*m/s

Answer 1

Solution:-

Given ,

• Velocity = 5m/s
• Momentum = 50 kgm/s

We need to find ,

• Mass of body = ?

As we know that ,

• Momentum = mass × velocity

Substituting known values we have ,

⇒ Momentum = mass × velocity

⇒ 50 = mass × 5

⇒ Mass = 50/5

⇒ Mass of body = 10kg

Hence , mass of body = 10kg

Answer 2

Given :-

• Velocity (v) = 5 m/s
• Momentum = 50 kg. m/s

To Find :-

• The mass of an object.

Solution :-

Momentum formula is given as ;

p = m × v

Here,

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

Units,

• p = kg.m/s
• m = kg
• v = m/s

[ Substitute the values in the formula ]

↪ 50 = m × 5

↪ m = 50/5

↪ m = 10 kg

Therefore,

The mass of an object is 10 kg.
