Question

Waterslide ride leaves the pool! The man in the innertube speeds down the waterslide at 34m/s. His entire ride, from the slide to stopping on the sidewalk, was 7 seconds long. What was his deceleration? (Show work)

Answer 1

His deceleration is
`-4.857`
`m/s^(2)`.

Step-by-step explanation:

The formula for acceleration is

`a=(v_(f)-v_(o) )/(t)`

We are given
`v_(f)`,
`v_(o)`, and
`t`.

Lets solve for
`a`.

`a=(0-34)/(7)`

`a=(-34)/(7)`

`a=-4.857`
