Show every unit, step by step on how they can cell out and explain in detail. Please! is to study for my test
Definitions: u) 21 Motion C-Level 1. Aicraft landing on a carrier are slowed down by arrest At constant acceleration ing wires from a speed of 170 mph (76.0 m/s) with a ·Av = at, oru, vit at constant acceleration of magnitude 24.53 m/s. What . -Vit + at2, or x1 = zit vit + rat2 is the distance required to stop the aircraft? (Follow tif + 2a- the steps below.) B) Write the three formulas for motion at constant acceleration C) For ALL variables in the 3 formulas state their values, if they are known, or state whether they are not known D) Then, for each formula explain why it can or e answer E) Now, find the distance F) If you haven't done this yet under E), check care- fully whether the units in your equations resolve to the units of distance. Further evaluate your answer (trend, limiting cases, order of magnitude, ...)Explanation / Answer
B) v = u + a*t --(1)
v^2 - u^2 = 2*a*d --(2)
d = u*t + 0.5*a*t^2 (3)
C)
here, initial speed, u = 76 m/s
final speed, v = 0
acceleartion, a = -24.53 m/s^2
distance travelled, d = ?
D)
equation 1 can not be used. beacuse d is is not present in the equation.
equation 2 can be used. Because d is there in the equation and other quantities are known.
equation 3 can not be used. Because d is there in the equation but t is unknown.
E) d = (v^2 - u^2)/(2*a)
= (0^2 - 76^2)/(2*(-24.53))
= 117.73 m
F)
