A man leaves his front door, walks 840 m east and 240 m north, stopping at the edge of a cliff. He then takes a penny from his pocket and drops it from the cliff, which is 10 m high. What is the magnitude of the displacement (in meters) of the penny?

Displacement of the person = ?(840^2+240^2)

= 873.61 m

Displacement of penny = ?( 873.61^2+10^2)

= 873.667 m
