In 2nd Question, in the second method when finding the area of the semi-circle why is it ‘pi (AH) squared’ shouldnt it be ‘1/2 pi (AH)squared’ ??

I think you made an error in question number 6(iii) . Isnt it that u have to account the time from when the passenger goes higher than 90m until the passenger is coming down back again to 90m ? In short, to find the time period spent being above 90m

this is what i did also 🙂

thanks a lot <3
