If the jet is moving at a speed of \( 1040 \mathrm{~km} / \mathrm{h} \) at the lowest point of the loop, determine the minimum radius of the circle so that the centripetal acceleration at the lowest point does not exceed \( 6.3 \mathrm{~g} \) 's. Express your answer to two significant figures and include the appropriate units. Part B Calculate the \( 70-\mathrm{kg} \) pilot's effective weight (the force with which the seat pushes up on him) at the bottorn of the circle, and at the top of the circle (assume the same speed). Express your answers using two significant figures separated by a comma.
