Question

question 15 of 25
a horse of mass 180 kg gallops at a speed of 8 m/s. what is the momentum
of the horse?
a. 1955 kg·m/s
b. 1440 kg·m/s
c. 22.5 kg·m/s
d. 845 kg·m/s

Explanation:

Step1: Recall the formula for momentum

Momentum \(p = mv\), where \(m\) is mass and \(v\) is velocity.

Step2: Substitute the given values

Given \(m = 180\space kg\) and \(v=8\space m/s\), then \(p=(180)(8)\).

Step3: Calculate the product

\(180\times8 = 1440\space kg\cdot m/s\)

Answer:

B. \(1440\space kg\cdot m/s\)
