Question

an airplane flies eastward and always accelerates at a constant

An airplane flies eastward and always accelerates at a constant rate. At one position along its path it has a velocity of 28.1 m/s, it then flies a further distance of 50100 m and afterwards its velocity is 49.1 m/s. Find the airplane's acceleration and calculate how much time elapses while the airplane covers those 50100 m. Acceleration: Elapsed time:

Answer 1

given

u=28.1 m/s

v=49.1m/s

s=50100m

$v^{2}-u^{2}=2as$

$a=\frac{v^{2}-u^{2}}{2s}$

$a=0.016m/s^{2}$

in three significant figure

time of elasped

$v-u=at$

$t=\frac{v-u}{a}$

$t=1312.5s=1310s$

in three significant figure
