Set 1: Quadratic Equations (Intermediate)

Explanation

Answer: A

Which coefficient in h(t)=at2+vt+h0h(t) = at^2 + vt + h_0 represents the acceleration due to gravity?

A.

aa

✓ Correct
B.

vv

C.

h0h_0

D.

None

Detailed Explanation

Choice A is correct. Choice A is the correct answer. In physics, the term at2at^2 comes from 12gt2\frac{1}{2}gt^2. The coefficient aa represents half of the gravitational acceleration (which is negative). Choice B is incorrect because it is velocity. Choice C is incorrect because it is height. Choice D is incorrect.

Key Steps:

The correct answer is aa

Why others are wrong:
B: Choice B is incorrect and may result from a calculation error.
C: Choice C is incorrect and may result from a calculation error.
D: Choice D is incorrect and may result from a calculation error.
