Answer 2

Explanation:

A) 1) 746 watt

2)Retardation means negative acceleration.

B) The SI unit of acceleration is the metre per second squared (m s−2); or "metre per second per second", as the velocity in metres per second changes by the acceleration value, every second.

SI unit: m/s², m·s−², m s−²

Dimension: L T −²

C) The law of conservation of energy is a law of science that states that energy cannot be created or destroyed, but only changed from one form into another or transferred from one object to another.
