Answer: (1,1)
Step-by-step explanation:
Answer:
Her centripetal acceleration during the turn at each end of the track is 
Step-by-step explanation:
Total distance covered in one round , D= 400 m
Time taken to cover one round , T = 1 min 40 s = 100 sec
Speed of runner , 
Now centripetal acceleration is given by

where 


Thus her centripetal acceleration during the turn at each end of the track is 
Answer:
1
Step-by-step explanation:
CosASinB + SinACosB
Sin(A+B)
Sin(35+55) = Sin(90) = 1
