Question

Manita carries a box of mass 40 kg.What is the weight of the box?(g=9.8m/s square​

Answer 1

Answer:

Mass of boy = 40 kg

Vo) 4GT 63

Mass of box = 20 kg

Total mass = 60 kg

Initial potential energy = 0 (since height would be O initially)

Final potential energy = mgh

Taking g as 10 m/s²,

=> 60 × 10 × 15

Vo) 4GT 63

= 9,000 J

So, work done = final potential energy - initial potential energy

= 9,000 J

Power = Work/Time

=> Power = 9000/25=> 60 × 10 × 15

Vo) 4GT 63

= 9,000 J

So, work done = final potential energy - initial potential energy

= 9,000 J

Power = Work/Time

=> Power = 9000/25

1=> Power 9000/25

=

Vo) 4GT 63

=> Power = 360 J/s

or 360 watt.
