An airplane's rate of climb is just the rate of increase in its
distance above sea-level. Suppose that an airplane is just
pulling out of a dive and its rate of climb changes from - 10 m/s to
+ 10 m/s in just one second. What is its vertical component of acceleration?
(A) - 10 m/s
(B) +10 m/s
(C) + 20 m/s
(D) - 20 m/s
(E) 0

+ 10 m/s in just one second. What is its vertical component of acceleration?
(A) - 10 m/s
No.
That is its initial vertical velocity component.

pulling out of a dive and its rate of climb changes from - 10 m/s to
+ 10 m/s in just one second. What is its vertical component of acceleration?
(D) - 20 m/s No.
[(10 m/s) - (-10 m/s)]/(1s) = [10 m/s + 10 m/s]/(1s).
