Question

A roller coaster starts off with an initial speed of 6.0 m/s and ends with a speed of 70 m/s over 4 seconds. What's the acceleration?

Answer 1

`16 s^(2)or16 {ms}^( - 2)`

Step-by-step explanation:

Formula for finding acceleration=

`a = (v - u)/(t)`

a,acceleration -?

v,final velocity - 70 m)s

u,initial velocity - 6.0 m/s

t,time - 4 seconds

`a = (70 - 6.0)/(4) \\ = (64)/(4) \\ =16 {ms}^(-2)`
