A150 kg object takes 1.5 minutes to travel a 2,500 meter straight path. it begins the trip traveling 120 m/s and decelerates to a velocity of 20 m/s. what was its acceleration?

-1.11 m/s²

Explanation:

v = at + v₀

Given v = 20 m/s, v₀ = 120 m/s, and t = 1.5 min = 90 s:

20 m/s = a (90 s) + 120 m/s

a = -1.11 m/s²

-1.11 m/s²

Explanation:

A 150 kg object takes 1.5 minutes to travel a 2,500 meter straight path. It begins the trip traveling 120 m/s and decelerates to a velocity of 20 m/s. Its  acceleration was -1.11 m/s².
