Information that is given: a = -5.4m/s^2 v0 = 25 m/s --------------------- S = ? Calculate the S(distance car traveled) with the formula for velocity of decelerated motion: v^2 = v0^2 - 2aS The velocity at the end of the motion equals zero (0) because the car stops, so v=0. 0 = v0^2 - 2aS v0^2 = 2aS S = v0^2/2a S = (25 m/s)^2/(2×5.4 m/s^2) S = (25 m/s)^2/(10.8 m/s^2) S = (625 m^2/s^2)/(10.8 m/s^2) S = 57.87 m
Science is based on theories and tests, if someone has a theory they will test and if it is correct yippie! and if it isn't they will redo the test over until they get it correct or unless it is unsolvable.
Plasma can be artificially generated by heating a neutral gas or subjecting it to a strong electromagnetic field to the point where an ionized gaseous substance becomes increasingly electrically conductive.
