Question

The height of a ball dropped from a 160 foot building after 1 seconds is represented by h(t) = 160 - 1612

How high will the ball be after 3 seconds?
A. O feet
B. 9 feet
C. 16 feet
D. 112 feet
E. 151 feet

Answer 1

C. 16 feet.

Explanation:

How to find the maximum height of a projectile

if α = 90°, then the formula simplifies to: hmax = h + V₀² / (2 * g) and the time of flight is the longest.

if α = 45°, then the equation may be written as:

if α = 0°, then vertical velocity is equal to 0 (Vy = 0), and that's the case of horizontal projectile motion.
