Explanation Given Info : Acceleration a ( t ) = e t i + 2 t j + ( t + 1 ) k Initial velocity v ( 0 ) = 1 i + 0 j + 1 k Initial position r ( 0 ) = 2 i + 1 j + 1 k Formula Used: (i) Apply the formula for velocity vector v ( t ) = ∫ a ( t ) d t + C 1 (iii) Apply the formula for position vector r ( t ) = ∫ v ( t ) d t + C 2 Here, all alphabets are in their usual meanings. Calculation: Apply the formula for velocity v ( t ) = ∫ a ( t ) d t + C 1 v ( t ) = ∫ { e t i + 2 t j + ( t + 1 ) k } d t + C 1 v ( t ) = e t i + t 2 j + ( t 2 2 + t ) k + C 1 − − − − − ( i ) Now, we shall apply given condition for initial velocity vector in equation (i) to calculated the integral constant ‘C 1 ’ 1 i + 0 j + 1 k = v ( 0 ) = 1 i + 0 j + 0 k + C 1 o r , C 1 = 1 k − − − − − − ( i i ) From equation (i) and (ii), the required expression for velocity vector v ( t ) can be calculated as v ( t ) = e t i + t 2 j + ( t 2 2 + t ) k + ( 1 k ) v ( t ) = e t i + t 2 j + ( t 2 2 + t + 1 ) k − − − − ( a ) v ( t ) = { e t , t 2 , ( t 2 2 + t + 1 ) } Apply the formula for position vector r ( t ) = ∫ v
