A truck running along a straight line increases its speed uniformly fr

1.	A truck running along a straight line increases its speed uniformly from 30 m/s to 60 m/s over a time interval 1 min. The distance traveled during this time intervals isa) 900mb) 1800mc)2700md)3600m
Answer» u=15 m/s v=30 m/s t=1 Min=60 s 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 =2.7 KM

A truck running along a straight line increases its speed uniformly from 30 m/s to 60 m/s over a time interval 1 min. The distance traveled during this time intervals isa) 900mb) 1800mc)2700md)3600m

Answer»

u=15 m/s

v=30 m/s

t=1 Min=60 s

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

=2.7 KM
