Ответ:
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.
Ответ:
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:
g = acceleration of gravity = 32.16ft / s ^ 2
Then the equation sought is:
Finally:
The correct option is the last option
