Question

A man walke towards the bus stop 100 meters away at a constant velocity. He reaches the bus stop in 200 seconds. Once at the bus stop, he sits for 500 seconds waiting for the bus. He then realizes he forgot something and runs home at a speed of 2.0 meters/second.

What is the velocity, displacement, and the time?

Answer 1

First:

d = 100 m
t = 200 sec

v = 100/200 = 0.5 m/s

Displacement is zero since he returned to his start point.

t2 = d/v2 = 100/2 = 50 sec

total time = 50 + 200 + 500 = 750 sec
