Physics - Relative velocity
posted by Shaila on .
A barge is heading directly across a river at35km/h while you are walking on the barge at 4km/h in the same direction as the barge is heading. The current is flowing downstream at 1.4km/h.
a) What is your velocity relative to the shore? (7.6km/h)
b) What would you velocity be relative to the shore if you were walking towards the shore you left? (1.5km/h)
Can any please check if the bracket answers are correct!!
a) No of course not. If the barge is going 35km/hr whether you are walking or not, in still water, the relative velocity is 35km/hr
velocity relative to shore is the vector sum
