- A trough is 5 meters long, 1.5 meters wide, and 1 meters deep. The vertical cross-section of the trough parallel to an end is shaped like an isoceles triangle (with height 1 meters, and base, on top, of length 1.5 meters). The kg trough is full of water (density 1000- ). Find the amount of work in m3 joules required to empty the trough by pumping the water over the top. (Note: Use g = 9.8 as the acceleration due to gravity.) s2 5m 1.5m 1mAn object moves with kinetic energy 18 J at ground level (where potential energy = 0), and moves 2 meters up a ramp, generating 4 J of heat (due to friction) during this process. If its kinetic energy is 5 J after this process, then what is its new potential energy in units of Joules (J)?An 210kg drone hits the ground at 311km/h and penetrates to a depth of 81.0cm.What was the force the ground exerted on the drone?
