Answer:
The angular acceleration and angular displacement is and 31.34 rad .
Explanation:
Given :
Initial linear speed , u = 9.8 m/s .
Final speed , v = 2.2 m/s .
Time taken , t = 3.4 s .
Radius of wheel , r = 0.65 m .
So , decelerates of wheel is given by :
Therefore , angular velocity is given by :
Now , linear displacement is :
Therefore , angular displacement is :
Hence , this is the required solution .
Answer:
A. Both the girl and the boy have the same nonzero angular displacement.
Explanation:
Since girl and boy both are standing on the same merry go round so here we can say that boy and girl both will revolve with same angular speed as the speed of the merry go round
so the angular displacement is given as
so here since both has same angular speed that is the speed of the disc so they both will turn by same angle in the same interval of time
So we have correct answer as
A. Both the girl and the boy have the same nonzero angular displacement.
