Question

u=20km/hr
v=80km/hr
t=4min,
find a and s
where
u=initial velocity
v=final velocity
t=time
a=acceleration
s=distance​

please give the ans in km/hr and please do not give the ans in decimal​

Answer 1

Answer:

from v=u+at

80=20+a×4

-20+80=a×4

60=a×4

a=15

from s=ut+1/2at²

s=20×4+1/2×15×4×4

s=80+120

s=200m
