When the amount of work done is 8 joule or 8 Kg m2/s2 for the initial mass m and unit of time t;
therefore the new mass is 2m and the new time is t/2.
Since, mass can be assumed to be the same, then as per the formula for calculating the amount of work –
=8 (Kg/2) x m²/ (2t)²
=8/8(KGM²/t²)
=1 Joule of work.
therefore the new mass is 2m and the new time is t/2.
