Question

The position x of a particle varies with time as x=3t^2 - 4t +5 where x is in meters and t is in second, then speed of particle at t =2 s is​

Answer 1

Answer:

10 m/sec

Explanation:

At t=0 put value of t in x equation and find position at t=0 . The find position at t=2sec and substrate the both positions to get the distance travelled in 2 sec.
