Question

a motorcycle at a stoplight takes 4.22 seconds to accelerate to 28.0 m/s after thew light turns green. what is its average acceleration

Answer 1

i think its 6.635 not very sure, sorry if it doesn't help.

Answer 2

6.64 m/s^2

Step-by-step explanation:

Average acceleration is defined as follows:

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

where

v is the final velocity of the object

u is the initial velocity

t is the time taken to accelerate from u to v

In this problem, we have:

`u=0 m/s` (the motorcycle starts from rest)

`v=28.0 m/s` is the final velocity

`t=4.22 s` is the time taken

Substituting numbers into the formula, we find

`a=(28.0 m/s-0)/(4.22 s)=6.64 m/s^2`
