I am answering this question because you're beautiful.
Ok
here
Initial velocity =60Km/hr
Final velocity =45 km/hr
Total time (of retardation)
=10seconds
=1/6 minutes
=1/36 hours
So as we know
Retardation
=
(final Velocity- initial velocity)/Time
=45-60/1/36
= -15×36km/hr^2
= -540km/hr^2
hey beautiful let's go on a date in hell XD
