Q:
# A bird experiences an acceleration of -1.80 m/s2 for 3.81 s, and ends up 26.5 m to the left of its starting point. What is its final velocity?

Accepted Solution

A:

Answer:-10.4 m/sStep-by-step explanation:Given:x = -26.5 mx₀ = 0 ma = -1.80 m/s²t = 3.81 sConstant acceleration equation:x = x₀ + v₀ t + ½ at²-26.5 = 0 + v₀ (3.81) + ½ (-1.80) (3.81)²v₀ = -3.53The initial velocity was -3.53 m/s. So the final velocity is:v = at + v₀v = (-1.80) (3.81) + (-3.53)v = -10.4 m/s
