Now you may go on:
PLEASE NO PHYSICS FORMULAS: I AM TRYING TO SOLVE THIS USING THE INTEGRAL AND THE MVT. THANKS.
A car is traveling at 100 km/h when the driver sees an accident 80 m ahead and slams on the breaks. What constant deceleration is required to stop the car in time to avoid a pileup?
What I think I know:
I am looking for : a(t)=(v2-v1)/t
Where: v1=initial velocity=100 km/h
v2=terminal velocity=0 km/h
t=time= unknown.
But first I need to find where s(t)=80m in order to find the time.
This is where I seem to be stuck...do I take the first Integral of a(t) or the second and use it as s(t)? Or is there something else I'm missing?
Thank you in advance!
