The velocity of car incrases from 30kmph in 5m. assuming the acceleration to be uniform calculate the distance travelled

We have, 
speed(v)=35kmph=9.72 m/s (approx)
time(t)=5mins

by using
v=s/t

9.72=s/5
9.72*5=s
48.6m=s
   or
s= 48.6 metres

Hope it helps
Don't feel shy and say thx

Julia would be observing a. static electricity was caused by her sweater rubbing against her shirt and transferring electrons. she didn't touch anything metal, so that would cancel out b.she most likely didn't rub her sweater against her hair either, so that cancels out c.she also didn't scoot across the carpet while trying to take her sweater off, that cancels out d.so that leaves a.a. is correct.
