Question

give that good answer

Answer 1

$<B><I>$given data :
*Mass of the Bolt m = 0.3 kg
*speed of the elevator= 7m/s

since the relative velocity of the boat with respect to the lift is zero at the time of impact potential energy gets converted into heat energy

heat energy= loss of potential energy= mgh
= 0.3×9.8×3= 8.82J

the heat produced to will remain the same even if the lift is stationary this is because of the fact that the relative velocity of the boat with respect to the lift will remain zero
