Question

A boat takes off from the dock at 2.5m/a and speeds up at 4.2m/s/s for 6.0 s. How far has the boat traveled? Round answer to nearest whole number

Answer 1

91 m

Step-by-step explanation:

v₀ = 2.5 m/s

a = 4.2 m/s²

t = 6.0 s

Find: Δx

Δx = v₀ t + ½ at²

Δx = (2.5 m/s) (6.0 s) + ½ (4.2 m/s²) (6.0 s)²

Δx = 90.6 m

Rounded to the nearest whole number, the distance traveled is 91 m.
