Pelle who weights 68 kilos, cycles up a steep hill. He stands up and pushes all his weight on the pedals. Pedals moves in a circle with the radie 18cm. Which is the biggest momentum he can affect the pedals with
Well my answer is wrong but this is how I did
Because I don't know the answer I take
m2= 9,82*(0,18)^2 = 0,318168/6,67*10^-11 = 4770134933
Which is the second mass
M1 = His weight 68kg
Then I take 68*4770134933 =3,24691754^10*-11 * 6,67*10^11 = 21,635424
and then I finely dived it which is 21,635424/0,18^2 = 667,76 N
I get but it's not right answer should be 120Nm please help me !
