An airplan moves on the runway of the airport at aconstant acceleration,then it takes off after it travels 1.5 km on the runway at avelocity of 210 km/h . what is the acceleration of airplane?
for constant accleration we can use v2 = u2 + 2as u=0 , a=? , v=210km/h=58.33m/s & s=1.5km=1500m a = v2/2s =(58.33)2/2(1500) =1.1m/s2
for constant accleration we can use
v2 = u2 + 2as
u=0 , a=? ,
v=210km/h=58.33m/s &
s=1.5km=1500m
a = v2/2s
=(58.33)2/2(1500)
=1.1m/s2
