Question

a car moving along a straight road increase its speed uniformly 15 metre per second to 30 metre per second over a time interval of 1 minute find the acceleration and the distance travelled by it in this time interval

Answer 1

u=15 m/s
v=30 m/s
t=1 minute=60s
a=v-u/t
=30-15/60
=15/60=1/4 m/s2
s=ut+1/2 at2
=15 (60)+1/2*1/4*60*60
=900+450
=1350 m
