You (50 kg) are standing on a floating log (200 kg). both are floating down a river at 1 m/s. the log points in the direction along the river. you walk in a direction that is down river for 5 seconds and your speed is 1.5 m/s as measured by a ground observer at the end of the 5 seconds.
a. what is the speed of the log at the end of the 5 seconds?
b. what is the average force between you and the log during those 5 seconds?
Answers: 2
= Mass of person = 50 kg
= Mass of log = 200 kg
= Velocity of person = 1.5 m/s
= Velocity of log
