The man pushes the lawn mower at a steady speed with a force P which is parallel to the incline. The mass of the mower with attached grass bag is 50 kg with mass center at G. If θ = 15o , determine the normal forces NB and Nc under each pair of wheels B and C. Neglect friction. Compare with normal forces for the conditions of θ = 0o and P = 0.

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.

it is called kinetic energy

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.

b. a lightning bug, plug of grass, and a worm
