What is the momentum of a 76-kilogram horse running at a speed of 45 kilometers/hour?
a) 2.5 x 10^2 kilogram-meters/second
b) 3.4 x 10^4 kilogram-meters/second
c) 3.4 x 10^3 kilogram-meters/second
d) 9.5 x 10^2 kilogram-meters/second

Momentum of horse,

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,

.......(1)

So, putting the values of m and v in equation (1) gives :

p = 950 kg m/s

or

Hence, the correct option is (D).

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
