Question

The motion of a particle is described by the equation u equals a t. The distance travelled by the particle in the first 4 seconds

  1. 4 a  
  2. 12 a  
  3. 6 a  
  4. 8 a  

The correct answer is: 8 a


    u equals a t comma x equals not stretchy integral blank u blank d t equals not stretchy integral a t blank d t equals fraction numerator a t to the power of 2 end exponent over denominator 2 end fraction
    For t equals 4 blank s e c comma x equals 8 a
