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?
Where does package hit the ground relative to the point
A flowerpot falls off a windowsill and falls past the window below. You may ignore air resistance. It takes time 0.420s to pass this window, which is of height 1.92 m. How far is the top of the window below the windowsill from which the flowerpot ..
