The initial velocity of an object is u =3 i +2 j m/s. Its constant acceleration is a =5 i +3 j m/s ^2 . The magnitude of the final velocity after 5 s is

Step-by-step solution

Using the equation of motion v = u + a t Substituting the given values: v = (3 i + 2 j ) + (5 i + 3 j ) 5 v = (3 i + 2 j ) + (25 i + 15 j ) v = 28 i + 17 j m/s The magnitude of the final velocity is: | v | = 28^2 + 17^2 | v | = 784 + 289 | v | = 1073 m/s Answer: 1073
