However, our approach will not assume constant acceleration; we use energy conservation:0220002()11GM rrGMmGMmmvmvvrrrr−−=−¡=which yields v= 1.4 ×106m/s. (b) We estimate the height of the apple to be h= 7 cm = 0.07 m. We may find the answer by evaluating Eq. 13-11 at the surface (radius rin part (a)) and at radius r+ h, being careful not to round off, and then taking the difference of the two values, or we may take
