The acceleration of the flea as it extends its legs is 1,000 m/s² The given parameters; final take off speed of the flea, v = 1 m/s distance covered by the flea, d = 0.5 mm The acceleration of the flea is calculated by applying the third kinematic equation;
where; v is the final velocity of the flea u is the initial velocity of the flea a is the acceleration of the flea The acceleration of the flea is calculated as;
Thus, the acceleration of the flea as it extends its legs is 1,000 m/s²
