Question

A cyclist is riding his bike up a mountain trail. When he starts up the trail, he is going 8 m/s. As the trail gets steeper, he slows to 3 m/s in 1 minute. What is the cyclist’s acceleration?

Answer 1

-0.08 m/s^2 , just answered this question

Answer 2

The cyclist's acceleration is -0.08 m/s².

Step-by-step explanation:

Given that,

Speed
`v_(i) = 8\ m/s`

Speed
`v_(f)= 3\ m/s`

Time = 1 sec

We know that,

The formula of acceleration is defined as:

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

Where, a = acceleration

`v_(f)`= final speed

`v_(i)`= initial speed

We substitute the value into formula

`a = (3-8)/(60)`

`a= (-5)/(60)`

`a = -0.08 m/s^2`

Hence, The cyclist's acceleration is -0.08 m/s².
