The trough in the figure below has width w = 5 ft, length L = D (Click on the graph for a larger version.) 19 ft and height h = 8 ft. If the trough is full of water, find the force of the water on a triangular end. (Use the density of water = 62.4 lb/ft³.) Force = Don't forget to enter units Find the work to pump all of the water over the top of the trough. Work = Don't forget to enter units

A sodium ion (Na+) moves in the xy-plane with a speed of 2.90 ✕ 103 m/s. If a constant magnetic field is directed along the z-axis with a magnitude of 3.25 ✕ 10−5 T, find the magnitude of the magnetic force acting on the ion and the magnitude of the ion's acceleration. HINT (a) the magnitude (in N) of the magnetic force acting on the ion  N (b) the magnitude (in m/s2) of the ion's acceleration  m/s2
