Acrate of mass 9.4 kg is pulled up a rough incline with an initial speed of 1.52 m/s. the pulling force is 94 n parallel to the incline, which makes an angle of 20.2° with the horizontal. the coefficient of kinetic friction is 0.400, and the crate is pulled 5.02 m. (a) how much work is done by the gravitational force on the crate?

This is a form of winter precipitation. it is frozen precipitation falling as ice pellets. snowflakes melt into raindrops as they pass through a thin layer of warmer air. the raindrops then refreeze into particles of ice when they fall into a layer of sub-freezing air near the surface of the earth. this precipitation is called a) hail. b) rain. c) sleet. d) snow.
