Question

A mass of object 5kg moving with the speed 3 m/s Find the momentum
​

Answer 1

Answer:

Given :-

mass of object = 5kg

speed = 3m/s

momentum p = mv

=> p = 5 × 3

=> p = 15 kg m/s

Answer 2

$\large{\underline{\underline{\pmb{\sf{\;Understanding\; the\; question\;:}}}}}$

• Here, we're given with the mass of an object and the speed with which it's moving. We've been asked to calculate it's momentum. The question is quite simple, we just need to equate all the values given in the question to the momentum formula. Let's first examine the formula for momentum in order to move further—

$\large{\underline{\underline{\pmb{\sf{\; Formula\; used\;:}}}}}$

» Momentum is a vector quantity characterized by the product of mass and velocity vector of the object. In simple words the momentum deals with the quantity of the motion. The formula of momentum is given by:

$\qquad\qquad\star~{\underline{\boxed{\pmb{\frak{p=mv}}}}}$

where:

• p is the momentum.
• m is the mass of object.
• v is the velocity of object.

$\large{\underline{\underline{\pmb{\sf{\; Solution\;:}}}}}$

Here, the question states that the mass of an object is 5 kg with an velocity of 3 m/s. So, equating this values in the formula, we get:

$\twoheadrightarrow\quad\sf{p=5\times 3}$

Now, performing multiplication in order to calculate the momentum of the object.

$\twoheadrightarrow\quad\underline{\boxed{\pmb{\frak{p=\red{15\; kg\; m/s}}}}}$

❝Therefore, the momentum of the object is 15 kg m/s.❞
