A roller coaster starts down the slope at 4 m/s. But 3 seconds later at the bottom of the slope it's speed is 22 m/s. What is the average acceleration?

x=6 m/s/s

Answer: 6m/s²

Step-by-step explanation:

Let

Initial Velocity be V_0 = 4m/s

Time be t = 3s

Final Velocity be V_n = 22m/s

Acceleration be A = (Final Velocity - Initial Velocity) / time

A = (V_n - V_0) / t

= (22 - 4) / 3

= 18/3

= 6m/s²
