A cyclist maintains a constant velocity of
5.2 m/s headed away from point A. At some
initial time, the cyclist is 257 m from point A.
What will be his displacement from his
starting position after 47 s?
244.4m
To find the cyclist's displacement from his starting position after 47 seconds, we need to determine how far he has traveled in that time.
We know that the cyclist maintains a constant velocity of 5.2 m/s. Velocity is defined as the rate of change of displacement, so we can calculate the distance traveled by multiplying the velocity by time.
Distance = Velocity * Time
Distance = 5.2 m/s * 47 s
Now we can calculate the distance:
Distance = 244.4 m
Since the cyclist is traveling away from point A, his displacement will be negative. The displacement is the straight-line distance from the starting position to the ending position, taking into account direction.
Therefore, the cyclist's displacement from his starting position after 47 seconds will be -244.4 m.
