C) 9 kilogram meters/second
Explanation:
The impulse is defined as the integral of the force over the time:
in a force-time graph, the impulse corresponds to the area under the curve. Therefore, in this case we can calculate the impulse by finding the area of the triangle.
The base is 3 s, while the height is 6 N, therefore the area (and the impulse) is
Answer:
3503.72 seconds
819.96 seconds
Explanation:
=Velocity of river = 0.566 m/s
=Velocity of student = 1.17 m/s
Distance to travel = 1.57 km = 1570 m
So,
Time = Distance / Speed
Time taken by the student to complete the trip is 3503.72 seconds
In still water
The difference in time between moving water and still water is 3503.72-2683.76 = 819.96 seconds
