in this que
initial velocity u=20
final velocity v=35
apply formula
v=u+at
but first convert into m/s
as t is in s
put values
and u will get a i.e acceleration
mark me brainliest
u=20 km/h
v=35km /hr
time = 5 sec = 5/3600hour
using equation
v=u+at
35=20+a*5/3600
u will get the answer
and by using equation
d=ut +1/2at^2
u can get d answer
