Question

An aeroplane on a runway, starts from rest and picks up a velocity of 180 km/h and takes off.
In doing so, it covers a runway of 1.5 km. Calculate (i) the uniform acceleration acting on the
aeroplane and (ii) the time in which it takes off.
[(i) 0.83 m/s 2 (ii) 60 s]​

Answer 1

Answer:

Fire doesn't fall into liquid, because it doesn't have a fixed volume. Fire doesn't fall into solid, because it doesn't have a fixed shape. Thus, fire is currently considered a plasma.

Answer 2

$\mathfrak{ANSWER}$$\mathfrak{ANSWER}$

$First, we will convert all units to a simpler form(180*1000)m/(1*60*60)sec = 50 m/s1.5 km = 1500 mD = 1500 mv(Final velocity) = 50 m/su(Initial Velocity) = 0 (Given)[B]Velocity(V) = Distance Covered(D) / Time taken(T)So , T = D/VT = 1500/50 = 30 seconds[A]Acceleration = (v-u)/t = (50-0)/30 = 5/3 m/s^2$
