Question

Calculate power generated by tension in the
in first 2 seconds of motion :-
uu
(1) 250 W
(2) 500 W
(3) 750 W
(4)1000 W​

Answer 1

Answer:

1000w

because power generation by tension in the first 2 second 1000w

Answer 2

Explanation:

power=force•velocity is invalid here because the question asks to find average power, not instantaneous.

power=change in kinetic energy/total time is also invalid here because it will give you average power generated in the mass of 10kg, not the string.
