Answer:
Displacement will be 11 revolution and 1.02π radian
Step-by-step explanation:
We have given that initial angular position = 0.45 radian
Angular speed
Time is given as t = 8.8 sec
So angular displacement in 8.8 sec
As he has already covered 0.45 radian
So total angular displacement = 0.45 + 71.8432 = 72.2932 radian
We know that 1 revolution = 2π = 2×3.14 = 6.28 radian
So 11 revolution = 11×6.28 = 69.08 radian
Left dispalcement = 72.2932 - 69.08 = 3.2132 radian = 1.02π radian
