5-58.

Answer parts (a) through (c) of the previous problem when $t = 210$ seconds and $e = 4080$ feet.

You will need to show steps:
part (a) $e\left(120 \text{ seconds}\right) ≈ 16$
part (b) $T\left(4080 \text{ feet}\right) ≈ −0.003, −0.004 \text{ or } −0.005$ (depending on which method you use)
part (c) $T\left(210 \text{ seconds}\right) ≈ −0.068, −0.087 \text{ or } −0.05$ (depending on which method you use)
