A solid object of mass 4.00 kg and specific heat capacity 835 J kg-'K is initially at height ho speed 6.00 m s1. When it hits the ground at h = 0.00 m, it stays there and its temperature rises by 5.00 x 10-2 K due to internal friction. Also, while falling from ho to h1, 25.0 J was transferred to the air by drag. Starting from the initial position ho, and assuming no other effects, which one of the following is false? (NB assume g = 10.0 m s-2) (A) AE = -72.0 J (D) AE = -25.0 J 3.00 m above the ground and falling vertically at (B) AE, = -120 J (E) Q = 167 J (C) W = -25.0 J %3D A solid object of mass 4.00 kg and specific heat capacity 835 J kg-'K is initially at height ho speed 6.00 m s1.
