Answer:
If effort distance was 4 times, efficiency would be 100%.
Since it takes 5 times for effort distance, efficiency drops to output/input
output is 1*F
input is (1/4*F)*5
so: F/1/5*F/4 = 4F/5F = .8 or 80%
Answer:
Part a)
Part b)
Explanation:
Part a)
As we know that initially the position vector is r
then the same magnitude position vector is rotated by 40 degree angle
so displacement magnitude is the magnitude of change in position vector
so it is given as
Part b)
now we need to find the direction of the displacement vector
so let say it makes an angle with x axis so we have
