I'm not sure what equation to use for this question could anybody help me? Final velocity - initial velocity = 2 * acceleration * distance
Or
Kinetic energy = 1/2 * mass * speed^2

BTW the answer to the first part is 13500J​

When the force acting on an object points at least partially in the direction of the motion the work done is considered to be negative

How can waves travel through ground?

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.
