Arocket is launched at 85 ft./s from a launch pad that’s 28 feet above the ground. which equation can be used to determine the height of the rocket at a given time after the launch? (answer choices in picture)

is equation of height of rocket at given time after the launch.

D is correct.

Step-by-step explanation:

A rocket is launched at 85 ft./s from a launch pad that’s 28 feet above the ground

We have an equation of rocket launching.

Where, g is acceleration due to gravity

v is initial velocity

h is initial height

h(t) is function of height at any time t

A rocket is launched by 85 ft/s

Substitute the value into formula ans get formula

Hence, D is correct. Equation of height of rocket at given time after the launch.

The correct option is the last option

Step-by-step explanation:

The kinematic equation to calculate the position of a body on the vertical axis as a function of time is:

Where:

= initial position = 28ft

= initial velocity = 85 ft / s

g = acceleration of gravity = 32.16ft / s ^ 2

Then the equation sought is:

Finally:

The correct option is the last option

the answer is 24
