Question

A body was moving with 60 Km/hr and attained a speed of 72 Km/hr in 20 seconds. Find the
acceleration of the body and distance travelled ?​

Answer 1

Explanation:

v=u+at

a=(v-u)/t -----------(1)

v=72 km/h

=20m/s

u=0

t=5*60 sec =300sec

by putting values of v,u,t in (1)

a=1/15 m/s2

s=ut +(1/2)at2

=0+(1/2)(1/15)(300)(300)

=3km
