Work, Energy and Power 10. Sheila has just arrived at the airport and is dragging her suitcase to the luggage check-in desk. She pulls on the strap with a force of 190 N at an angle of 35° to the horizontal to displace it 45 m to the desk. Determine the work done by Sheila on the suitcase. 11. The first asteroid to be discovered is Ceres. It is the largest and most massive asteroid in our solar system's asteroid belt, having an estimated mass of 3.0 x 10²¹ kg and an orbital speed of 17900 m/s. Determine the amount of kinetic energy possessed by Ceres. 10 The Tainal 104 to 1667 & fall 101
