Answer:
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
Answer:
165.529454
Explanation:
According to the Pythagorean Theorem for calculating the lengths of a right angle triangle's sides, a^2 + b+2 = c^2, where c is the longest side (and the side opposing the right angle). So in your case it would be 150*150 + 70*70 = 27400. And √ 27400 is your answer.
Neither they’re both moving the same . 150/3 = 50km
100/2 = 50km
therefor they’re traveling at the same rate.
