Calculating Deceleration Rate of a Car

AI Thread Summary
The discussion focuses on calculating the deceleration rate of a car using initial and final velocities along with the stopping distance. The formula v² = u² + 2as is highlighted as a key equation for determining acceleration or deceleration. Participants emphasize the importance of understanding Newton's laws of motion for solving such physics problems. Additionally, there is a query about how to calculate the stopping distance from a different initial speed of 60 km/h. Overall, the thread serves as a resource for beginners seeking to grasp basic physics concepts related to vehicle deceleration.

I apologize for my ignorance, I'm an extreme newbie in physics.
Is it possible to determine the deceleration rate of a car only with following information?

initial velocity = 60mph (96km/h)
final velocity = 0mph (0km/h)
distance = 146ft (44.5m)

if so, how many distance would it take to stop from 60km/h (37.5mph)?

Thank you

v^2=u^2+2as

v=Final velocity
u=initial velocity
a=acceleration
s=displacement.
 
do a search for Newton's laws of motion. they are probably the most well known equations for scientists and engineers and worth remembering. there are a few other derivations than the one that rock freak has given you.
 
thanks a lot guys!
 
This has been discussed many times on PF, and will likely come up again, so the video might come handy.

Thread 'Is 'Velocity of Transport' a Recognized Term in English Mechanics Literature?'
Here are two fragments from Banach's monograph in Mechanics I have never seen the term <<velocity of transport>> in English texts. Actually I have never seen this term being named somehow in English. This term has a name in Russian books. I looked through the original Banach's text in Polish and there is a Polish name for this term. It is a little bit surprising that the Polish name differs from the Russian one and also differs from this English translation. My question is: Is there...
Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...
