A horse has a momentum of 25 kg*m/s and a velocity of 2.5 m/s. What is the horse mass?

 10 kg

Work Shown:

We have these variables

p = momentum = 25 kg*m/sm = mass = unknownv = velocity = 2.5 meters per second

Solving for the mass gets us...

p = m*v

25 = m*2.5

25/2.5 = m

10 = m

m = 10

The mass of the horse is 10 kg.

This is what i found on google “according to the collision theory, the following criteria must be met in order for a chemical reaction to occur: molecules must collide with sufficient energy, known as the activation energy, so that chemical bonds can break. molecules must collide with the proper orientation.” i hope this information you.
