Question

an aeroplane on a Runway starts from rest and picks up a velocity of 180 km/hour 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.​

Answer 1

Answer:

uniform acceleration is 1.66m/s^2

time taken is 30s

Explaination :

velocity = 180Km/ hr = 50 m/s

displacement = 1.5Km = 1500m

Velocity = change in displacement (ds)

_________________________

time (t)

t= ds/v = 1500÷50

t = 30s = 0.00833hr

acceleration = change in velocity / time

= 50 / 30

= 1.66 m/s^2
