You are travelling at 60.0 mph on the grand central parkway near exit 10 where it is (nearly) parallel to the long island expressway (lie). a) a truck on the lie going in the same direction as you is travelling at 55.0 mph. what is your relative velocity compared to that truck? b) a truck on the lie going in the opposite direction as you is travelling at 55.0 mph. what is your relative velocity compared to that truck?

a)Vr= 5 mph

b)Vr= 115 mph

Explanation:

Lets

your velocity ,u= 60 mph

velocity of truck ,v= 55 mph

When object are moving in opposite direction the relative velocity  = u +v When object are moving in opposite direction the relative velocity  = u - v

a)

Truck is moving in the same direction ,so the  relative velocity

Vr= = u - v

Vr= 60 - 55

Vr= 5 mph

b)

Truck is moving in the opposite direction ,so the  relative velocity

Vr= = u+v

Vr= 60 + 55

Vr= 115 mph
