A1-kg ball dropped from 2 m rebounds only 1.5 m after hitting the ground. the amount of energy converted to heat is

ΔE = Ef - Ei = (Uf + Kf) - (Ui + Ki) = (mgh + 0) - (mgh +0)
ΔE = mghf - mghi = 1(9.8)(1.5) - 1(9.8)(2) = -4.9 J
The total energy of the system decreases by 4.9 J so that must mean that 4.9 J is converted into other forms of energy and in this case it is heat.

Iassume the answer is 75 feet. inwards to outwards rather than outwards to inwards. probably be 75.hachures are stokes drawn in direction of the steepest slope. a series of short parallel lines drawn on a map to indicate topographic relief. it is actually called hachures on contour lines. the small marks in the center of the feature are called hachures.observe the picture attached
