Question 100

At time t t\,t seconds a particle P P\,P has acceleration a=2ti−6j\mathbf{a}=2t\mathbf{i}-6\mathbf{j}a=2ti−6j m s−2^{-2}−2.

Initially its velocity is (3i+4j)(3\mathbf{i}+4\mathbf{j})(3i+4j) m s−1^{-1}−1 and its position vector is (i−2j)(\mathbf{i}-2\mathbf{j})(i−2j) m.

a.

Find the velocity of P P\,P in terms of ttt.

[3]
b.

Find the position vector of P P\,P when t=2t=2t=2.
