<h3>
Answer: 10 kg</h3>
==================================================
Work Shown:
We have these variables
- p = momentum = 25 kg*m/s
- m = mass = unknown
- v = 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.
