the acceleration of the bike.

Answer 1

`0.61 m/s^2`

Step-by-step explanation:

The bike's acceleration can be found by using the following suvat equation:

`v^2-u^2=2as`

where

v is the final velocity of the bike

u is the initial velocity

a is the acceleration

s is the distance covered

For the bike in the problem,

u = 0

v = 7 m/s

d = 40 m

Solving the equation for a, we find the acceleration:

`a=(v^2-u^2)/(2s)=(7^2-0)/(2(40))=0.61 m/s^2`
