What did youn guys get on the wheel question? Talking about P1 variant 12
For greatest height i subbed t=0 and got that h=60 m

And to show that k=1/15Pi i subbed h=0 and got it

Also for part iii of the question where you need to find the time when h=90 m i got values t=10 and t=20 but i wrote that the right time was t=10

Greatest was 120

Second part was easy

III part men 90 would come twice...hence 10 and 20 both correct
