Answer to Question #9739 in Mechanics | Relativity for prakhar
his dog.when he saw her approaching,dog was
exited and dashed to her,then back to his master
and so on,never stopping.how far would you estimate the dog ran if its speed is 30km/hr and each of them walked at 4km/hr;starting
400 m apart?
They will meet in:
t = S / V, where S = 400m, V = V1 +
t = 400 / (4000 + 4000) = 0.05hrs
The distance made by the dog is:
= t * Vd, where Vd = 30km/hr
D = 0.05 * 30 = 1.5km
