Question

A ball of mass 200 g in motion along a straight line with a velocity of 81 km/h. What is its momentum?

Answer 1

Hola User________________

Here is Your Answer.....!!!!!!
_________________________⚓〽

〽⭐↖↖Actually welcome to the concept of the MOMENTUM. ...

〽↖↖⭐Basically we know that ...MOMENTUM = MASS × VELOCITY ....

〽↖So as given here ...

⚓M = 200g = 0.2 kg ...

⚓V = 81 km/hr = 45/2 m/s . ..=====》 22.5 m/s
so there fore we know that

〽↖⤵p = MV

〽⤵⤵p = (0.2) × ( 45/2) ======》 9

========》⤵⤵ 4.5kg m/s.....

〽⤵⤵there fore ...momentum = 4.5kg m/s ...

Bonjour ❤️

$\huge \boxed{ \mathbb{ \ulcorner ANSWER: \urcorner}}$

✴️ first we have to change the units of mass and velocity into its SI unit.

✅Mass = 200g = 0.2kg

✅Velocity = 81 km/h = 22.5 m/s

now,

✔️MOMENTUM = M × V

P = 0.2 × 22.5

= 4.5 kg.m/s

hence, momentum of the ball = 4.5kg.m/s
