Question

if a person covered a certain distance in 5min at a speed of 72km/h.find the distance travelled .​

Answer 1

HELLO MATE

Given :

Initial Velocity=u=0m/s

Final velocity= V= 72km/h

Time =5 min =5/60 h =1/12 h

acceleration=a=?

As we know that , a=v-u/t

⇒a=72-0/1/12

=72*12

=864km/h²

Distance travelled  =s=ut+1/2at²

=0x1/12 +1/2(864)(1/12)²

=(1/2)x864x(1/144)

=3km

Distance covered by person is 3km
