Question

A boat travels 11.3 m while it reduces its velocity from 19.0 m/s to 1.9 m/s. What is the magnitude of the boat's acceleration while it travels the 11.3 m?

Answer 1

-15.8 m/s²

Step-by-step explanation:

Given:

s = 11.3 m

u = 19.0 m/s

v = 1.9 m/s

Find: a

v² = u² + 2as

(1.9 m/s)² = (19.0 m/s)² + 2a (11.3 m)

a = -15.8 m/s²
