(C)
Explanation:
The circle has a radius r = 0.5 m, which means that its circumference C is
One revolution means that the stopper travels a distance equal to the circumference of the circle so the velocity of the stopper is
Average acceleration over a time interval lasting is
where is the difference in the jet's final and initial velocities. It's coming to a rest, so
so the average acceleration has magnitude 8.9 m/s^2 and is pointing West (the direction opposite the jet's movement, which should make sense because the jet is slowing down).
Answer:
F = 9.82 N
Explanation:
given,
Force x-component = 5.69 N
Force y-component = 8 N
magnitude of force = ?
Resultant of force
F = 9.82 N
Hence, the magnitude of force is equal to 9.82 N
