use kinematic equation,
v=u+at
where v is the final velocity
u is the initial velocity
a is the acceleration
t is the time
now given ,
v=72 km/h =72 x 1000/3600=72 x 5/18
=20m/sec
u=36 km/h = 36 x 5/18 =10m/sec
time =1 hour =3600 sec
now,
20=10 +a(3600)
10=3600 a
a=10/3600=1/360 m/sec^2
v=u+at
where v is the final velocity
u is the initial velocity
a is the acceleration
t is the time
now given ,
v=72 km/h =72 x 1000/3600=72 x 5/18
=20m/sec
u=36 km/h = 36 x 5/18 =10m/sec
time =1 hour =3600 sec
now,
20=10 +a(3600)
10=3600 a
a=10/3600=1/360 m/sec^2
