Writing Newton’s Second Law in the vertical direction, for the case where only the weight acts on Barb or Kenny (mass m), when they are going at speed v \[\begin{aligned} mg &= ma_R = m\frac{v...Writing Newton’s Second Law in the vertical direction, for the case where only the weight acts on Barb or Kenny (mass m), when they are going at speed vmg=maR=mv2R∴v=√gR=√(9.8m/s2)(22m)=14.68m/s This corresponds to the minimum speed that they must have at the top of the loop to make it around.
