Question

A body lying initially at point (3,7) starts moving with a constant acceleration of 4i cap. Its position after 3 sec is given by coordinates?

Answer 1

POSITION VECTOR = 3I CAP+7J CAP ACC.=4I CAP TIME=3 SEC X(T)=X(0)+U*T+1/2*A*T*T X(T)=3I^+7J^+0*3+1/2*4i^*3*3 X(T)=3i^+7J^+0+1/2*4i^*3*3 X(T)=21i^+7J^
