If you divide a force measured in newtons (1 new- ton = 1 kg•m/s?) by a speed expressed in meters per
second, in what units will the answer be expressed?

The magnitude of the poynting vector of a planar electromagnetic wave has an average value of 0.939 w/m^2 . the wave is incident upon a rectangular area, 1.5 m by 2.0 m, at right angles. how much total electromagnetic energy falls on the area during 1.0 minute?

The force it would take to accelerate an 900-kg car at the rate of 6m/s2

Which describes increasing the efficiency of energy resource
