It's not same quantity.Check dimension. Vector have the dimension of velocity and the scaler have that of time.(time is scaler) thus the final vector will have dimension of distance and that is different quantity.
Yes sir i got it tysm.Then can we find its magnitude?
Yup. The magnitude can be found. Scaler can be directly multiplied to vectors.Like :- ( i + j )(velocity) X 4 (time)= 4i + 4j (displacement)Magnitude will be = root(x^2 + y^2) = 4root(2).
Thank you Sir.
