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

Answer:

6.64 m/s^2

Explanation:

Average acceleration is defined as follows:

$a=\frac{v-u}{t}$

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

$a=\frac{28.0 m/s-0}{4.22 s}=6.64 m/s^2$
