- A box containing basketball equipment is sitting on a shipping pallet. The box plus the contents weighs 25 newtons [N], and the pallet weighs 155 newtons [N]. The box can be modeled as a rectangular parallelepiped and has the following dimensions: 3 inches [in] by 15 inches [in] by 20 inches [in]. Assume the pallet is also a rectangle and has the following dimensions: 4 feet [ft] by 3.5 feet [ft] by 0.25 feet [ft]. The box is sitting on the pallet in the configuration shown. You apply 9000 joules [J] of energy to push the box and the pallet across the floor using 160 newtons [N] of force. Determine how far you can push the box and pallet, in units of feet [ft]. You may ignore the friction between the court and the pallet.The planet Jupiter has a mass of 1.9 × 1027 kg and a radius of 72,000 km.
