The wheelbarrow shown has a mass of 35.0 kg without the wheel. When it is empty, the center of mass is 0.400 m from the axle. A load with a mass of 55.0 kg is put in the wheelbarrow, 0.600 m from the axle. Olivia holds the handles of the wheelbarrow, 1.20 m from the axle. She lifts the handles so that they make a 25.0° angle with the ground. What is the upward force that Olivia applies to the handles in order to hold the wheelbarrow in that position?
