Three forces \( \vec{F}_{1}, \vec{F}_{2} \) and \( \vec{F}_{3} \) are acting on a particle of mass \( 10 \mathrm{~kg} \).
\( \mathrm{P} \) The particle moves in \( x-y \) plane such that its coordinates are given by \( \left(5 t^{2} \mathrm{~m}, 15 t^{2} \mathrm{~m}\right) \). Find:
W
Acceleration vector of the particle
(1) \( (5 \hat{i}+15 \hat{j}) \mathrm{m} / \mathrm{s}^{2} \)
(2) \( (10 \hat{i}+30 \hat{j}) \mathrm{m} / \mathrm{s}^{2} \)
(3) \( (10 \hat{i}+25 \hat{j}) \mathrm{m} / \mathrm{s}^{2} \)
(4) \( (5 \hat{i}+30 \hat{j}) \mathrm{m} / \mathrm{s}^{2} \)
