show work please.

average velocity from pillar to post. 2.5 Starting from the front door of a ranch house, you walk l 60.0 m due east to a windmill, turn around. and then slowly walk 40.0 m west to a bench, where you sit and watch the sunrise. It s takes you 28.0 s to walk from the house to the windmill and then 36.0 s to walk from the windmill to the bench. For the entire trip r from the front door to the bench, what are your (a) average velocity and (b) average speed? 26 A Honda Civic travels in a straight line along a road The

Explanation / Answer

a)

The average velocity is given by

Displacement/time

Displacement is 60-40=20m

Time taken =tw+te =36+28 =64s

Then the average velocity is =20m/64s =0.3125m/s

b)

The average speed is given by

=total distance/time

total distance =60+40 =100m

total time taken=Time taken =tw+te =36+28 =64s

then =100m/64s =1.5625m/s
