A body is moving with a constant acceleration of 4i+3j, starting from rest from the origin. What will be the position of the body after 5s?

The body’s displacement is given by $s=\left(1/2\right)a{t}^2$ . The body starts from the origin hence, the total displacement is the final position of the body. Therefore, after putting in the values, we get $s=\left(1/2\right)\left(4\widehat{i}+3\widehat{j}\right)*5^2=50\widehat{i}+37.5\widehat{j}.$
