Amass of 14 kg is accelerated at 2m/s2 for a distance of 5 meters. how much energy is required?

Force = mass * acceleration

= 14 * 2 = 28N

Work done (energy) = Force * distance

= 28 * 5 = 140J

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.
