After 2.0s, isabela . was riding her bicycle at 3.0m/s on a straight path. after 5.0s she was moving 5.4m/s. what was her acceleration?

Her acceleration was  0.8 m/s².

Explanation:

Given data:

Final speed v₂ = 5.4 m/s

Initial speed v₁= 3.0 m/s

Initial time t₁ = 2 s

Final time t₂ = 5 s

Acceleration = ?

Solution:

acceleration = (v₂- v₁) / (t₂ -  t₁)

acceleration = 5.4 - 3 / 5-2

acceleration = 2.4 / 3 = 0.8 m/s²

if you're asking what comes out, it's steam.

the answer is b. dilution
