-Initial velocity of the BODY = 0 m/sVelocity after 10 sec = 4 m/sTo FIND :-The displacement covered by the body.Analysis :-Firstly substitute the given values in the question using the first EQUATION of MOTION and find the acceleration accordingly.Then using the second equation of motion substitute the values we got and find the displacement accordingly.Solution :-Using the formula,We know that,v = Final velocityu = Initial velocitya = Accelerationt = Time takenGiven that,Final velocity (v) = 4 m/sInitial velocity (u) = 0 m/sTime taken (t) = 10 secSubstituting their values,⇒ a = (v-u) / t⇒ a = (4 - 0) / 10⇒ a = 4/10⇒ a = 0.4 m/s²Using the formula,We know that,s = Displacementu = Initial velocityt = Time TAKENA = AccelerationGiven that,Initial velocity (u) = 0 m/sTime taken (t) = 10 secAcceleration (a) = 0.4 m/s²Substituting their values,⇒ s = 0 × 10 + (1/2) × 0.4 × 10²⇒ s = (1/2) × 0.4 × 10²⇒ s = (0.4 × 100) / 2⇒ s = 40/2⇒ s = 20 mTherefore, the displacement is 20 m.
