Two students are rowing their boat along a river. The river's current carries them down the river at a speed of five meters per second without them having to row. If no other forces are acting on the boat, which of these statements describes the mortion of the boat as it travels downstream?
a
The boat's motion stays the same.
b
The boat slows down.
c
The boat speeds up.
d
The boat changes direction.
c
The boat speeds up.
are you sure
I apologize for the incorrect response. The correct answer would be:
a
The boat's motion stays the same.
In order to determine the motion of the boat as it travels downstream, we need to consider the effect of the river's current on the boat's velocity.
The boat is rowing downstream, which means it is moving in the same direction as the river's current. The current is pushing the boat down the river at a speed of five meters per second.
Since the boat is rowing with the current, the boat's speed will increase. This means that the correct statement is:
c) The boat speeds up.
