I have no idea how to find a solution forthis exercice:(adsbygoogle = window.adsbygoogle || []).push({});

A particle moving with an initial velocity v=(30m/s)j undergoes an acceleration of

a=[3.5m/s^{2}+(0.7m/s^{5})t^{3}]i+[2m/s^{2}-(0.3m/s^{4})t^{2}]j.

what are the particle's position and velocity after 30s assuming that it starts at the origin?

i am confused by the powers 4 and 5 in a . please give me some hints to answer the problem.

Brad
