it should be a -8.

the equation b should be 200= (1/2)(-16)t^2+v0(t)

200= -8t^2+v0t

** in the equation for displacement, before we solve for A, acceleration should be replaced not by 16, but -16 because this is deceleration.

Answers by Expert:

All topics in first-year calculus including infinite series, max-min and related rate problems. Also trigonometry and complex numbers, theory of equations, exponential and logarithmic functions. I can also try (but not guarantee) to answer questions on Analysis -- sequences, limits, continuity.

I taught all mathematics subjects from elementary algebra to differential equations at a two-year college in New York City for 25 years.**Education/Credentials**
