A racing car going at 20m/s stop in distance of 20m what is its acceleration ​

acceleration (a) =?

initial velocity (u) =20m/s

final velocity (v) =20m

time taken (t) =?

we know that

a= v–u/t

a=20–20/t

a=0m/s

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.
