Question

A particle is moving such that its position coordinates x , y are 2 m , 3 m at time t = 0 , 6 m , 7 m at time t = 2 s and 13 m , 14 m at time t = 5 s . The average velocity vector V → a v from t = 0 to t = 5 s is:, 1 5 13 i ^ + 14 j ^, 7 3 i ^ + j ^, 2 i ^ + j ^, 11 5 i ^ + j ^

The position vector of the particle at time t = 0 is r → i = 2 i ^ + 3 j ^ The position vector of the particle at time t = 5 s is r → f = 13 i ^ + 14 j ^ The displacement of the particle is s → = 11 i ^ + 11 j ^ The average velocity vector V → = 11 i ^ + 11 j ^ 5
