While driving south on hwy 400, Jim gets stuck travelling at 1.9 m/s behind a slow truck. He finally gets into a passing lane, hits the gas and speeds up with a constant acceleration of 0.060 m/s2. What is his velocity (m/s) after accelerating for 8.5 km?

Respuesta :

Final velocity

[tex]vf\approx\text{ 31.99 m/s}[/tex]

Data & Formula:

. final velocity: vf = ?

. initial velocity : vi = 1.9 m/s

. acceleration : a = 0.060m/s^2

. distance : d = 8.5 km

[tex]vf\text{ = }\sqrt[]{vi^2+2ad}[/tex]

[tex]vf\text{ = }\sqrt[]{1.9^2\text{ + 2 }\cdot\text{ 0.060 }\cdot\text{ 8.5}}[/tex]
