A roller coasters accelerates at 2 m/s from an initial velocity of of 6.0 m/s for 5 seconds. What is its final velocity?

Hello user!

Hence, the acceleration = 16 m/s^2

Steps:

Given:

Initial velocity (u) = 6 m/s

Initial velocity (u) = 6 m/sFinal velocity (v) = 70 m/s

Initial velocity (u) = 6 m/sFinal velocity (v) = 70 m/sTime (t) = 4 seconds

To find:

Acceleration (a) = ?

Solution:

Acceleration (a) = Final velocity (v) - Initial velocity (u) ÷ Time (t)

(putting values)...

--> a = 70 - 6 ÷ 4

--> a = 64 ÷ 4

--> a = 16 m/s^2
