Answer:
Momentum of horse, [tex]9.5\times 10^2\ kg-m/s[/tex]
Explanation:
It is given that,
Mass of the horse, m = 76 kg
The speed of the horse, v = 45 km/h
Converting km/h to m/s, i.e. v = 12.5 m/s
The product of mass of horse and the velocity with which it is moving give its momentum. Mathematically,
[tex]p=m\times v[/tex].......(1)
So, putting the values of m and v in equation (1) gives :
[tex]p=76\times 12.5[/tex]
p = 950 kg m/s
or
[tex]p=9.5\times 10^2\ kg-m/s[/tex]
Hence, the correct option is (D).
