Question

What is the momentum of an object of mass 500g, moving with velocity 8 m/s ?

Answer 1

Solution :-

Given :-

• Mass = 500 g = 0.5 kg
• Velocity = 8 m/s

To Find :-

• Momentum

Formula Used :-

• $\underline{ \boxed{ \pink{ \sf Momentum = Mass \times Velocity}}}$

Substituting Values

$\sf \implies 0.5 \: g \times 8 \: m {s}^{ - 1}$

$\sf \implies \cancel{\dfrac{5}{10} } \times 8\times kg \times m {s}^{ - 1}$

$\sf \implies \dfrac{1}{ \cancel{2}} \times \cancel{8}\times kg \times m {s}^{ - 1}$

$\sf \implies 4\times kg \times m {s}^{ - 1}$

Therefore, 4 kg m/s

Hence, Solved ♡

Answer 2

Aɴsᴡᴇʀ:

• The required momentum of the object = 4 kg m/s

Gɪᴠᴇɴ:

• The mass of the object = 500 gram
• The mass of the object = 0.5 kg
• The velocity of the object = 8m/s

Nᴇᴇᴅ ᴛᴏ ғɪɴᴅ:

• The required momentum of the object = ?

Solution:

Fᴏʀᴍᴜʟᴀ ᴜsᴇᴅ ʜᴇʀᴇ:

• Momentum = Mass × Velocity

Pᴜᴛᴛɪɴɢ ᴛʜᴇ ᴠᴀʟᴜᴇs:

➦ Momentum = 0.5g × 8 ms^-1

➦ Momentum = 5/10 × 8 × kg × ms^-1

➦ Momentum = 1/2 × 8 × kg × ms^-1

➦ Momentum = 4 × kg × ms^-1

Tʜᴇʀᴇғᴏʀᴇ:

• The required momentum of the object is 4 kg m/s.
