Question

two particles of same mass moving at a speed of 10 metre per second and 54 kilometre per hour. Then ratio of the momentum will be?​

Answer 1

Answer:

p=mv

so m is constant in both

one is in m/s and another is in km/hr

Explanation:

so first change one and then solve it

Answer 2

Here is your Answer

given values are,

first particles velocity is 10m/s and mass is (m)

so momentum is p = mv

p = 10m

Now second particles velocity is 54km/h it means 54000/(60×60) = 15m/s

so momentum is p = 15m

Now the ratio of the momentum is

$\frac{10m}{15m } \\ = > \frac{2}{3}$

I hope that is right answer
