Question

The velocity of an object is given by v vector 6t cube ICAP + t-square J cap metre per second find its acceleration at time is equal to 2 second

Answer 1

Answer:

Explanation:as we know acceleration is dv/dt

So we diffrentiate v vector 6tcubei+tsq.j

18t2i+2tj

By putting t-2sec

18(2)2i+2(2)j

72i+4j. Ans
