(b) If the coconut from the shorter tree takes time T to reach the reaches the ground with a speed V, whal Ill of V) of th ground, how long (in terms of 7) will it take the other coconut to reach the ground? 2.7 Relative Velocity Along a Straight Line 58. I A Toyota Prius driving north at 65 mi/h and a VW Passat driving south at 42 mi/h are on the same road heading toward each other (but in different lanes). What is the velocity of each car relative to the other (a) when they are 250 ft apart, just before they meet, and (b) when they are 525 ft apart, after they have passed each other?

Explanation / Answer

Given

Toyota Prius moving with v1 = 65 mi/h to North

ane Passat moving with v2 = 42 mi/h to South

means both are heading each other on a straight road

we know that the relative velocity( velocity of each one relative ot the other) on straight line if the objects are moving with velocities v1,v2 is

V_rel = V1+V2

so here

relative velocity of each car relative ot the other is V_rel = 65+42 = 107 mi/h

though they are very close before they are going to meet and after they have passed each other the relative velocity does not change

a) 107 mi/h

b) 107 mi/h
