Question

A car comes to rest when break was applied for 3s to get a retardation of 2m/s2. Calculate how far the car would have travelled after applying a break? pls answer fast....​

Answer 1

see it's given

t= 3 sec

v= 0 (since the car stops)

then we have a= -2ms-²

we need to find s!!

so v=u+at

so from here we get the value of u as 6 metres

and then we find s by using

s=ut+1/2at²

and we get s = 9 metresss!!

there you go!

hope it helps..
