Answer 1

QUESTION ---- An aeroplane taking off from a field has a run of 500m.What is the acceleration and take off velocity if it leaves the ground 10s after the start??

ANSWER -----

Distance (s) = 500m
Initial velocity (u) = 0
Time (t) = 10 sec

Using second equation of motion :
s = ut + 1/2 at square

500 = 0 + 1/2 a × 10 × 10
500 = 50a

=> a = 10 m/sec square

Using first equation of motion :
v = u + at

v = 0 + 10 × 10

v = 100 m/sec

ANSWER = 100 m/sec
