Question

If a car at a speed of 36 km per hour from rest in 12 minutes what is distance covered

Answer 1

Answer:

Step-by-step explanation:

speed of car intially is 0   (at rest)  (u)

speed of car finally is 36km/hr=36*5/18  =2m/s  (v)

accelaration(a)=?

distance(s)=?

time (t)=12 minutes =12*60 = 720 sec

a=(v-u)/t

a=(2-0)/720

a=2/720 -------1

s=ut +1/2*at²

s=0 +1/2*2/720*720²

s=1/2*2/720*720*720

s=720m
